A program that shows the size of folders on a disk. Analysis of hard drive contents. Review of free programs

Good afternoon.

Very often users ask me the same question, but in different interpretations: “what is the HDD?”, “Why did the space on the hard drive decrease, because I didn’t download anything?”, “How to find files that are taking up space on the HDD?” etc.

For evaluation and analysis occupied space exist on the hard drive special programs, thanks to which you can quickly find everything unnecessary and delete it. Actually, this is what this article will be about.

Analysis of occupied hard disk space in charts

1. Scanner

Official site: http://www.steffengerlach.de/freeware/

Very interesting utility. Its advantages are obvious: it supports the Russian language, no installation required, high speed work (she analyzed a 500 GB hard drive in a minute!), takes up very little space on the hard drive.

The program presents the results of the work in a small window with a diagram (see Fig. 1). If you hover your mouse over the desired piece of the diagram, you can immediately understand what takes up the most space on the HDD.

For example, on my hard drive (see Fig. 1), about a fifth of the busy space is occupied by movies (33 GB, 62 files). By the way, there is quick buttons to go to the trash can and “add or remove programs”.

2. SpaceSniffer

Official site: http://www.uderzo.it/main_products/space_sniffer/index.html

Another utility that does not require installation. When starting, the first thing you will do is ask you to select a drive (specify a letter) to scan. For example, my Windows system disk has 35 GB of space, of which almost 10 GB is occupied by the virtual machine.

In general, the analysis tool is very visual, it helps you immediately understand what is clogged up on your hard drive, where the files are “hidden”, in which folders and on what topic... I recommend it for use!

3.WinDirStat

Official site: http://windirstat.info/

Another utility this kind of. It is interesting primarily because in addition to simple analysis and drawing up a diagram, it also shows file extensions, painting the diagram in the desired color (see Fig. 3).

In general, it is quite convenient to use: the interface is in Russian, there are quick links (for example, on emptying the recycle bin, editing directories, etc.), it works in all popular Windows operating systems: XP, 7, 8.

4. Free Disk Usage Analyzer

Official site: http://www.extensoft.com/?p=free_disk_analyzer

This program is the easiest tool for quick search large files and disk space optimization.

Free Disk Usage Analyzer helps you organize and manage your HDD free disk space by searching for the largest files on the disk. You can quickly find where the most large files, such as videos, photos and archives, and move them to another location (or delete them altogether).

By the way, the program supports the Russian language. There are also quick links that will help you clean your HDD from junk and temporary files, delete unused programs, find the largest folders or files, etc.

5.TreeSize

Official site: http://www.jam-software.com/treesize_free/

This program cannot create charts, but it conveniently sorts folders depending on the space occupied on the hard drive. It is also very convenient to find a folder that takes up a lot of space - click on it and open it in Explorer (see arrows in Fig. 5).

Despite the fact that the program is English language- dealing with it is quite simple and quick. Recommended for both beginners and experienced users.

By the way, significant space on your hard drive can be taken up by so-called “junk” and temporary files (by the way, they reduce the free space on your hard drive, even when you don’t copy or download anything to it!). It is necessary to clean your hard drive periodically special utilities: CCleaner, FreeSpacer, Glary Utilities etc. More details about such programs.

That's all for me. I would be grateful for additions on the topic of the article.

Good luck with your PC.

This is the one that over time there is little space. On the one hand, we bought ourselves 1 TB and it seems good, now everything will work. But over time, it turns out that it gets “clogged” and you don’t want to remove the old one (in case it comes in handy), but there is no place for a new one.
Then there comes a moment during which something can be freed. But sometimes this is not enough.
Then a reasonable question arises in my head: But what is taking up so much space on my disk?".

First of all, they “go” to the folders with films, then games and programs. And you have to remove them by grinding your teeth.

So, I won’t bore you, but I’ll write about several programs whose purpose is to show how many and which files (folders) take up the most space on your disk. Of course, all of them (like all the programs provided on my website) are free.

Looking ahead, I’ll tell you that the meaning is the same for everyone - to analyze the system and show in a visual form what and how it takes up space, while showing some additional capabilities. As a result, you can see and delete (if desired) unnecessary large files.

The first program to analyze a disk and search for large files and folders is WinDirStat.

After installation and launch, the main program window will look like this:

In it you can specify what exactly needs to be scanned: all drives, a specific drive or a separate folder.
After choosing (I chose one system disk) the scanning process will begin:

Which will produce the result. The program window is divided into 3 parts:
1 - result by folder
2 - result for files (types/) indicating their legend
3 - general diagram. The meaning is simple - the more space it takes, the larger the display.
For convenience, the results are shown in descending order, i.e. The "largest" files are displayed at the top.

This way you can clearly see which files and folders take up how much space on the disk.

Now let's look at what we can do with this information besides easy viewing, namely, pay attention to the top menu with buttons:

Since the program is in Russian and the buttons contain tooltips, I can only list what you can do with a folder or file directly from this program:

open in explorer;

copy path;

delete permanently (use this carefully);

remove to trash;

open element properties;

run file (or open folder):

Enlarge/reduce the diagram window for a more detailed view.

As you can see, all the most necessary functions.

By the way, using this program you can also check external and network drives.

Another one similar program- This JDiskReport.

It differs from the previous one primarily in the absence of the Russian language.
After launch, you will be prompted to select a directory to scan and open the saved analysis file.

You can specify the whole disk and go ahead:

The window is divided into two parts: the left one indicates the location, and the right one generates a diagram.

Let's deal with the left part.
It displays a list of directories sorted by "majority", i.e. The more space a folder takes up, the higher it is. It's the same story in the subfolders.

The right side is much more interesting.
At the bottom you can change the type of diagram (out of four provided) and enable the display of files (check Show files).
At the top you can switch to the 50 “best” files ( top 50), see how many files in size occupy certain spaces ( Size Dist), when and how many files were last modified ( Modified) and how much space certain types of files take up ( Types).
IN top menu The program itself is interested in only two switches: the first, for sorting alphabetically (and not by “majority”), the second to display the number of files (and not the volume).

But you can only view this information. To delete files, you will have to open Explorer and look for this folder or file there. But you can also right-click on the folder and select Open Explorer... to open.

The following program for analyzing and searching large files is Scanner.

The program differs from the previous ones in that it does not require installation (portable).

After launch, it immediately scans all disks and shows summary information:

You can select a specific drive, the scan result will show the volume of folders:

HDD Scanner (Scanner) is a free program with which you can get useful information: Find out the size of folders on a disk in the Windows operating system. The application clearly shows the size of the contents of your computer's disks.

The HDD Scanner program analyzes the content hard drives, CD/DVD drives connected to the computer external media (USB flash drives, external hard disks, etc.), and then displays in the form of a diagram the space occupied by files and folders on these disks.

Users who are active on their computer move a lot of data. During operation, free disk space gradually decreases. Therefore, questions arise about how much space each folder takes up.

Having received an answer to the question about the size of folders in Windows, you can rationally distribute folders and files across different drives and delete unnecessary data from your computer.

The free HDD Scanner (or simply Scanner) program displays on charts the amount of space occupied by folders and files. The chart shows the amount of space occupied by a disk, folder, subfolders, etc.

The Scanner program does not require installation on your computer. This is a portable (portable) program launched from a folder. Although latest version application was released in 2012, the HDD Scanner program works without problems in operating systems ah Windows 7, Windows 8, Windows 8.1, Windows 10.

The HDD Scanner program can be downloaded from the official website of the developer Steffen Gerlach, the application works in Russian.

hdd scanner download

After downloading the application, unzip the archive. Unpacked Scanner program takes up only 509 KB of disk space.

The HDD Scanner program is portable, so the folder with the application can be placed anywhere on the computer, or on a flash drive.

Using HDD Scanner

Launch the HDD Scanner program. After launch, the scanning process will begin, during which the program analyzes the disk space of this computer. The scanning process will take some time, which depends on the number of disks and the amount of space occupied by the data.

The program window displays all the drives connected to the computer; my computer has two hard drives (one hard drive is divided into two partitions), one external hard disk, CD/DVD drive.

During the first HDD startup Scanner scans all drives. Subsequent scanning of all disks will be faster.

After the disk analysis is completed, a diagram will appear in the application window, which clearly shows how much space is occupied by certain files and folders on the computer’s disks.

Hover your mouse over a specific location in the chart to view data about a specific folder. At the very top of the “Scanner” window (opposite the arrow) you will see the name of the folder or file, the space occupied in gigabytes or megabytes, and the number of files in this folder.

There are two buttons in the upper right part of the program window. The top button calls up the “Add or Remove Programs” function; using the bottom button you can empty the Trash.

In the lower right part of the program window, there are buttons for navigation: moving to the Parent folder, back, to update data in this folder.

How to add an item to launch HDD Scanner to the context menu

For permanent HDD usage Scanner on your computer, it is possible to add a program item to the context menu.

To do this, you first need to rename the folder with the “scn2” program to the “Scanner” folder. Next, place the “Scanner” folder in the “Program Files” folder, which is located on the “C:” drive. This location is equally suitable for 32 and 64 bit Windows operating systems.

There are two registry files in the Scanner folder.

Double-click on the registry file “Add Scanner to Context Menu».

Agree to launch Registry Editor. In the “Registry Editor” window with a warning, click on the “Yes” button to make changes to the registry.

After this, you will see a message stating that the values ​​contained in the file have been successfully added to the registry.

After you hover your mouse over any folder or drive in Explorer, context menu The “Show Usage with Scanner” option will be displayed.

After clicking on the “Show Usage with Scanner” item, the Scanner program will launch, which will display in its window a visual diagram of how much space data takes up in a specific folder or on a specific drive.

How to remove the HDD Scanner program item from the context menu

To remove a Scanner program item from the context menu, enter the “Program Files” folder, then open the “Scanner” folder. The folder contains the registry file “Delete Scanner from Context Menu”.

Run the “Delete Scanner from Context Menu” file and agree to the registry changes. After executing this command, the “Show Usage with Scanner” item will be removed from the context menu.

Conclusions of the article

The free HDD Scanner (Scanner) program is used to analyze and obtain information about the amount of space occupied by folders and files on computer disks. The information is presented in the form of a visual diagram.

Question “What is taking up so much space on my hard drive?” sometimes it can confuse you. It would seem that all the weighty folders with documents, music, films, and also installed programs we know, but... When we click on the “Properties” of the hard drive and look at the ratio of full and occupied space, we understand that there is an obvious inconsistency - several (or maybe a dozen or two) gigabytes of our precious disk space have disappeared somewhere.

In such cases, you can audit the contents of user profiles, check hidden system files and folders, page file size (Pagefile.sys), hibernation file (hiberfil.sys), folder System Volume Information that is stored control points system recovery, start the standard one Windows utility– “Disk Cleanup” and so on. But these manipulations are not always able to shed light on the truth.

This entry lists several programs whose function is to analyze the structure and volume of information that is stored on the computer's hard drive. For me personally, it is important that these programs are free, easy to use, and most importantly, provide reliable information. I suggest we take a closer look at the programs that meet the specified conditions.

SpaceSniffer is a portable, free program that helps you understand the folder and file structure of your hard drive. SpaceSniffer's visualization diagram will clearly show you where large folders and files are located on your devices. The area of ​​each rectangle is proportional to the size of that file. You can double click on any sector to get more detailed information about it. If you are looking for specific file types such as JPG files, or files older than a year, use the “Filter” option to select the conditions you specify.

The program has many settings, but its interface is in English. The information it produces seemed to me not very convenient for visual perception and, as a result, for evaluating it. But in principle, it works quickly and efficiently. In any case, once you get used to it and delve into the settings, it’s quite possible to use it.

WinDirStat collects information from the selected disk and presents it in three views. List of directories that resembles a tree structure Windows Explorer, displayed on the left top corner and sorts files and folders by their size. The extended list that appears in the upper right corner shows statistics about different types files. The file map is located at the bottom of the WinDirStat window. Each colored rectangle represents a file or directory. The area of ​​each rectangle is proportional to the size of the files or subtrees.

The program is not portable, but it has Russian-language interface. I didn’t delve too deeply into its settings, but one nuance immediately caught my eye - System folder Volume Information, according to the program, is empty. In fact, this is not the case, System Restore is enabled and a little over 3 GB is currently used for it. So the program lied.

TreeSize Free

Not portable, choice of two languages: German and English. Microsoft certified. Allows you to run a program in the usual way or from the context menu of a folder or drive. This is a very convenient opportunity, in my opinion. The program shows you the size of the selected folder, including subfolders. The results are presented in a Windows Explorer tree view, so you can expand the selected folder or drive and navigate to the file at each level. To analyze hidden system folders the program asked to restart the PC.

Disktective is free, portable utility, which reports actual size directories and the distribution of subdirectories and files in them. The selected folder or drive is analyzed and the result is displayed in the form of a tree and chart. The interface is English, information collection is fast.

The interface is English, not portable. DiskSavvy is a fast and easy-to-use disk space analyzer that allows you to monitor disk space usage on your computer. hard drives, network drives and NAS servers. The main window shows the percentage of disk space used by each directory and file. You can also easily view pie charts showing the results in graphic format. It has a large number of settings.

DiskSavvy is available as a free version, as well as a full, Pro version that provides additional features and technical support. The free version allows you to scan maximum amount files – 500,000, at maximum hard capacity 2 TB disk. He supports long names files, unicode file names and allows you to copy, move and delete files directly within the program. Cool program, I like it.

For each selected folder or drive, GetFoldersize displays overall size all files in this folder or disk, as well as the number of files and attachments in them. You can use GetFoldersize to scan unlimited quantity files and folders on internal and external hard drives, DVDs, and discs network resources. This program supports long file and folder names and unicode characters and has the ability to display file sizes in bytes, kilobytes, megabytes and gigabytes. GetFoldersize allows you to print a folder tree and save the information in text file.

Versions of GetFoldersize are available in both portable and installable versions, so you can carry it with you on a flash drive or external USB drive. However, if you install GetFoldersize, it will add to all its features the option to launch from the context menu in Windows Explorer, which will allow you to start scanning the volume of a folder or disk by right-clicking on it. Interface is English, a good choice settings.

RidNacs is a fast disk space analyzer that scans local drives, network drives or individual directories, displaying the results in a tree and percentage histogram. You can save scan results in several formats (.TXT, .CSV, .HTML, or .XML). Files can be opened and deleted directly in RidNacs. During installation, you can add the option to run the program in the Windows Explorer context menu. When you scan a folder, it is added to the list of favorite drives. You can also change appearance histograms by installing special skins (skins). The program is not portable; it has 2 interface languages ​​- English and German. She could not analyze some folders, as can be seen in the screenshot.

Portable Scanner shows a pie chart with concentric rings to show the space usage of your hard drive, external hard drive, network drive. Moving the mouse over the segments in the diagram allows you to display the full path to the object at the top of the window, as well as the size of the directories and the number of files in the directory. Right-clicking on a segment provides additional options. It is possible to delete selected directories to the Trash directly from the program. The archive with the program contains 2 reg files, one of which is used to add the scanner to the Windows Explorer context menu, and the other to remove it.

Free Disk Analyzer I liked it more than all other programs. During the installation process, you are offered a choice of 5 languages, Russian is present. Free analyzer Disk Drive displays drives on the left side of the window, similar to Windows Explorer, allowing you to quickly navigate to the desired folder or file. The right side of the window displays all subfolders and files in the selected folder or disk, the size and percentage of disk space that the folder or file uses. Tabs at the bottom of the window allow you to quickly select and view your largest files or folders. You can manage your files directly within the program, just like in Windows Explorer. Among the additional features, it is worth noting the launch of the program uninstaller, as well as the settings menu, which allows you to filter only certain files:

If you have previously had problems with “losing” disk space, tell us how and with the help of what programs (or actions) you solved them.

Absence free space on the hard drive - the problem is constant. With the purchase of a more capacious medium, this problem is not solved, but only worsened: the more information accumulates, the more difficult it is to control it and at the same time maintain a certain conventional order.

There are many utilities for finding duplicates, outdated and other unnecessary files, however service maintenance disk does not eliminate the need to independently “sort out the rubble.” These files, as often happens, are stored in folders different levels nesting. Using file manager tools for searches is one option. By the way, even standard Explorer has a filter and search available. However, there are more effective comprehensive solutions for disk space analysis. Typically they include features such as:

• Scan disks and directories
• Data visualization: display file structure as a chart, graph or map
• Advanced statistics and their export
• Search for duplicates, temporary files
• Filters and advanced search
• Additional tools

Today's guide participants are predominantly free programs. The exceptions are FolderSizes and TreeSize, although the latter also offers a free version in the Free edition. The resulting list of participants looks like this:

• TreeSize
• Scanner
• WinDirStat
• Space Sniffer
• JDiskReport
• Xinorbis
• FolderSizes

TreeSize Pro

TreeSize is a utility for finding files that waste disk space. Includes both information functions(visualization, statistics, export), and service: search for duplicates, outdated files and so on.

In the left panel of the TreeSize window there is a disk selection menu and a directory tree where navigation and selection of the scan source is carried out.

The results are displayed on the right side of the window, consisting of tabs. In the Chart section there is a diagram from which you can find out percentage directories within the selected source. It is also easy to change the display of data in the form of graphs or maps. detailed information about the directory (amount of data, space occupied, etc.) is available in the Details tab. Extensions - distribution of data according to their content: video, graphics, text and others. In Age of files - information about the age of files. In addition, it will be useful to analyze the chronology of disk filling (History). All data is available for export in XLS, CSV, HTML, TXT and other formats.

Top 100 contains a list of the largest files on the disk. The accompanying information in the columns of the table allows you to find out the date of the last access or creation of the file - this will help you decide whether to delete or leave the file.

No less interesting in TreeSize are the search (File Search menu). You can use all data types (All Search Types): this, in particular, includes searching for outdated, temporary files, and duplicates. The advantage of searching through TreeSize is undeniable: the program is multi-threaded, works over the network, and supports templates.

Alas, the free (essentially trial) version of TreeSize is significantly inferior to the paid version: multithreading, advanced search, visualization and many other important functions are not supported.

Summary. TreeSize Pro perfectly complements the capabilities of any file manager, allowing you to thoroughly analyze the occupied disk space and directories. Well customizable interface and search, visualization, export - standard set included.

[+] Functionality
[+] Advanced file search
[+] Fast multi-threaded scanning
[+] Additional tools

Scanner

Scanner free utility for analysis hard content disk. No settings, a minimum of options - nevertheless, Scanner is a completely functional solution.

In the left part of the window, you can select a disk for analysis; you can also get information in existing files on all disks using the “Total” button in the lower left corner.

In the center is pie chart, which displays file structure in the form of segments. Segments, as is easy to note, have several levels of nesting and different color. When you hover the cursor over a certain area of ​​the diagram, information about the number, size of files, and their location is available. You can move to the directory by clicking on it, or perform operations with the file through the context menu.

Summary. The program will be useful for a quick visual analysis of occupied disk space. As for the available operations with files and directories, they are only sufficient to delete and open files. In other words, you won’t be able to use Scanner as a file manager (with search, display modes, statistics).

[+] Ease of use, intuitiveness
[−] Minimum number of file operations

WinDirStat

WinDirStat is a free utility for analysis and cleaning hard disk from unnecessary files.

The program scans the specified sources (directories or local drives) and provides information for analysis in an easy-to-read format. The directory structure is displayed as multi-colored segments various sizes, according to the space occupied, at the bottom of the WinDirStat window. The table of color correspondence to the file type is in the upper right corner.

This structure representation has its drawbacks: for example, you cannot find out the file size when hovering, there are no marks. Therefore, in the case of WinDirStat there is not enough alternative ways visualizations such as graph and chart.

By clicking on a segment, you can get detailed information about the corresponding file and its location. The following files are available with: standard commands, such as deleting (to the Trash or permanently), viewing properties, copying the path and others. In the “Cleaning” section of the program settings, it is possible to create user actions, allowing you to add up to 10 operations from the command line: deleting files, archiving, recursive deleting and others.

In general, almost all WinDirStat settings come down to design, display of the structure and list of directories. Any additional utilities, tools for reporting, statistics, and search are not provided here.

Summary. WinDirStat provides good customization options, but the lack of additional tools and display modes significantly limits the program's use.

[+] Selective scanning
[+] Command line support
[−] One file display mode
[−] Lack of detailed statistics and reporting

SpaceSniffer

SpaceSniffer is a free utility with a fully customizable interface and data display mode in the form of a map. Compared to similar solutions, notable features include multithreading, search (including network search), and NTFS support.

For processing, you can select not only a disk from the list, but also a directory by specifying the path in the Path line. As a result of scanning, a map is formed in the form of blocks. The level of nesting can be adjusted using the Less/More Detail buttons - accordingly, the detail is reduced or increased. By clicking on a block, you can view its contents without going to the catalog. Navigating deeper through catalogs is no less convenient. Additional modes There is no display in SpaceSniffer, but you can customize the design to your liking through the main settings (Edit - Configure).

Statistics functions are presented modestly. If desired, you can export to a text file: summary information, a list of files, as well as files grouped into folders. Interestingly, reports can be created using templates.

Additional features include tags and a filter. Filtering is carried out using the specified mask; the syntax is described in the Filtering help section. You can search by size, folder name, tags, attributes and other data. Tags allow you to make selections from data for subsequent filtering and batch operations. They can be thought of as temporary bookmarks within a session.

Summary. SpaceSniffer does not stand out for its wide functionality, but it attracts with its speed of operation, fairly convenient display of data in the form of a map and additional tools such as filter and tags.

[+] Multi-window interface
[+] Integration with Explorer
[+] Filters and tags
[−] No search

JDiskReport

The free cross-platform utility JdiskReport analyzes which files take up the most disk space. In addition, the program provides statistics on the distribution of data, which can be viewed in the form of graphs and charts.

By selecting a directory or drive to scan, the user can view the collected information or save the result as a snapshot for later opening. This is relevant when permanent job with large amounts of data.

Statistics are divided into tabs: Size, Top 50, Size Dist, Modified and Types. The Size section shows the ratio of files in the selected source. There are several display modes to choose from: 2 types of charts, graph and table. Top 50 contains a list of the largest, oldest and newest files- potential “candidates” for removal. The Size Dist, Modified and Types sections allow you to view the distribution of files by their size, modification date and type, respectively.

On the one hand, the statistics really give food for thought, on the other hand, navigation through files and sample directories is not thought out in JdiskReport. That is, any file operations are not available, only the “Open Explorer…” item is available in the context menu. There is no export, except that the file table and related information can be copied to the clipboard.

The program settings are mainly responsible for the interface. There are plenty of design themes, but, say, there are no options for displaying columns or a directory tree.

Summary. JdiskReport outperforms Scanner and WinDirStat due to file distribution statistics. But there is also weak sides- first of all, there are no operations with files and directories.

[+] Statistics
[−] No export
[−] Non-functional context menu

Xinorbis

Xinorbis is a data analyzer on your hard drive with the ability to view statistics in the form of tables, charts and graphs. The program supports scanning to various sources: hard drives, removable media, software local network, FireWire, etc.

When selecting a scan source, you can specify multiple paths, include and exclude items, and add favorites. The scan results are displayed as a summary: this information will help you quickly determine the most big file or catalogue, familiarize yourself with the distribution of data by type, etc.

Detailed information is collected in the Folder properties section of the Tasks section. Data can be viewed in the form of custom graphs, charts, and structured by data type or file extension. Information about the age of data (Dates), chronology (History), and occupied size (Folders) is available. The Top 101 section contains a list of not only the largest and smallest files. The file table displays properties such as creation, modification, and last access dates.

The navigator context menu in Xinorbis is more than functional: it not only contains standard Explorer commands, but also provides for export, archiving, Hex editing, and checksum generation.

The Advanced section contains tools such as searching for duplicates by name and size. Other teams are also expanding search capabilities. The most interesting section is Folder Detail, which is a filter based on a number of parameters: text, size, file attributes, owner, category.

An important advantage of Xinorbis is customizable reports in HTML, CSV, XML and other formats. As a result, it takes just one click to create a file.

Summary. In Xinorbis it is most difficult to find shortcomings, since everything is taken into account standard features file analyzer: from creating charts to exporting reports.

[+] Reporting
[+] Filter and search
[+] Flexible setup and functionality

FolderSizes

FolderSizes is a program for scanning and analyzing disk space with the ability to export results as a report. Includes tools for searching files by multiple criteria: size, owner, age, etc.

The FolderSizes interface consists of several panels (navigator, drive list, graphs, address bar), as well as a ribbon divided into tabs. The main section is Home, where basic tools for analysis, export and other operations are available.

In the address bar you can specify not only the standard path, but also server or NAS devices, network and removable media(Analyze path(s) option). The file panel is flexibly customizable, columns are easy to hide or add additional ones. Scan results can be viewed as graphs, charts, or a map in the Bar Graph area. Extra options, related to displaying information in panels, are available in the Graph tab.

To create reports, use the File Reports tool, which searches based on specified criteria and displays detailed information in a human-readable format. Report export is available in HTML, PDF, XML, CSV, TXT and other formats, including graphic ones. FolderSizes can be easily linked to a scheduler to automatically generate scheduled reports.

In addition to standard reporting functions, FolderSizes offers trend analysis. The Trend Analyzer tool is designed for this and allows you to see changes in size, number of files and other criteria.

Filter and search with rule support, built-in archiver, command line- FolderSizes capabilities can be listed further. The functionality of the program is unrivaled.

Summary. FolderSizes pleases with the presence of all the tools necessary for analysis, user-friendly interface, additional features, which are not available in other programs (for example, trend analysis and archiver). As a result, it will be interesting for study by a wide audience.

[+] Fully customizable interface
