A program for finding duplicate files by extension. The files are duplicates of CCleaner. Functions and features of Soft4Boost Dup File Finder

Greetings, dear reader! Today I will show you a program that searches for identical files on the computer. The program not only finds copies of files, but also, at the user’s request, immediately deletes them. Very convenient in this regard. And there may be so many copies of files that you won’t even suspect it. They just might be in different folders and even on different drives. You may use some of them all the time, but you may have forgotten about their copies.

For example, they downloaded a picture from the Internet, used it for their own purposes and forgot about it. After some time, you needed this picture, but you were too lazy to look for it on the computer. It's easier to find it on the Internet. Download again and get a duplicate file that already exists on your computer.

The same can happen with music files. You downloaded it into different folders and think that you have it in a single copy. Many PC users make one mistake. When you grab a file with the left mouse button and drag it to another folder located on another disk, it is not moved, but copied. This means that the file remains in the same place, and in new folder there was a copy of it on another disk.

It turns out that one file is superfluous and only takes up free space in the computer’s memory.

Search for identical files

This program has flexible settings with which we can speed up the search.

Let's say we are looking only on one or two disks. We tick them and press the “Scan” button

But the program will find all files that have copies. But we don’t need this, because, for example, we only want to find images.

Search by file type

In this case, go to the “Files and Folders” tab. Check the file format boxes. Images come different formats, but the program offers us only four jpg, jpeg, gif, bmp. These are the most popular formats images that almost every user has.

The rest that are not in the list must be entered manually. Click the “Add” button. In the window that opens, enter required format Pictures. For example from the program Photoshop-(*.PSD)

OK! We scan and get a bunch of copies to delete. Stop! But they can be systemic. So let's move on.

We scan only the necessary folders

Let's select individual folders to scan. The program will only check them. At the bottom of the program there is a setting “Searched folders” Check the item “ Only specified folders"With such parameters, you don’t have to select the disk in the “Disks” tab. Yes, and don't forget to check the box here " Include these folders even if the corresponding drive is not selected «

We scan and get the result. Once the scan is complete, DupKiller will switch to the “List” tab, where all found duplicate files will be shown.

The files, in our case, are pictures, sorted into groups. A group consists of two or more files. They are all the same, as they are copies of each other.

Which files should I delete?

Click on any of the files in the group, and you will see a thumbnail image in the preview window. Now just scroll the mouse wheel to move through the list and compare copies with each other.

All information about the file is visible on the program screen. And even if the image is not displayed in the preview window, we can compare files by name, size and type. The first column, called "Path", shows the location of the file.

Deleting identical files

We look at this data and select one file in each group. Now the marked files can be deleted by clicking on the “Delete” or “” button. You can also use the “Delete” key on the keyboard to delete.

If there are too many files to delete, then it is better to use automatic deletion files. In this case, you choose from which folder to delete identical files. how it works? Highlight right key mouse one file in the group and click on the “Auto select” button

In the window that appears in the top block, the paths to folders in which there are similarities between the files will be displayed. The same folders are listed in the lower block, but are not checked. We need to select one of these folders in which the files should be deleted. Click “Ok”

There's another problem here. Each time you delete one of the copies, a confirmation window appears.
You are tired of confirming. Disable this notification by going to the “Delete” settings and uncheck the “ Ask for confirmation before deleting«

OK it's all over Now. I superficially showed you the principle of operation of the DupKiller program.

There is a desire to delve into additional settings « Search settings" And " Other settings«

And in my opinion, she does her job well.

Write in the comments how you like this program and how you clean disk space then unnecessary copies?

This is useful to know:


No matter how voluminous modern hard disks, alas, they don’t know how to stretch yet.

For those who like to randomly download various content to their computer, this means that sooner or later Windows will display a message about the impossibility of copying or saving a particular file due to lack of free space.

Program for finding duplicate files

In this case, willy-nilly, you have to make a choice: buy external hard disk, move files and DVDs, or simply delete some content to make room for new data. However, there is no need to rush. One of the most common reasons for lack of space on a hard drive is duplication of files.

It happens that a user, forgetting that a file has already been downloaded, downloads it again, possibly under a different name and with different metadata.

That’s why it’s so important to search for duplicate files before freeing the disk from “ballast.”

Duplicate Cleaner

This can be done using the Duplicate Cleaner program specially designed for finding duplicate files different types. Thanks to this powerful and effective tool, you can get rid of duplicate videos, audio, test files, photos and other types of files in a matter of minutes. From similar programs Duplicate Cleaner is different high speed and accuracy of work.

Anti-Twin

Duplicate Cleaner is not the only program that can find and remove duplicate files. Anti-Twin is free, quick utility looks for duplicates just as well.

The utility supports search by given criteria, match level (in percentage), image preview, quick transition to what was found and many other additional functions.

One of the features of this utility is the ability to compare two directories. Anti-Twin can be used as portable application. Unfortunately, Anti-Twin does not have the Russian language, so setting up some options may cause some difficulties for a user who is not familiar with English.

SMF – Search my Files

Quite powerful and functional program to find duplicates. Distinctive feature of this application - great amount various filters and settings. SMF – Search my Files supports searching by size, extension, metadata and many other criteria. Thanks to this application, you can extract and analyze alternative ADS streams from any file type.

Found duplicates can be deleted (including without the possibility of recovery), moved, copied, changed its attributes (hidden, read-only, archived, etc.). Export to test format, viewing and editing data in the built-in hex editor, search by command line. SMF – Search my Files does not require installation and can be launched from any media.

Bottom line

Which of these three duplicate finder programs is the best? Hard to tell. It all depends on what goals you are pursuing and what level of training you have.

Anti-Twin and SMF – Search my Files are good, but due to many specific functions they are more suitable for use experienced users and system administrators.

Removing duplicate files sometimes it takes a lot of time and effort, since this requires “over-hairing” a considerable amount separate files, folders, and sometimes even disks.

A program for finding duplicate files is most often needed by users who store on disk a large number of music, photos and documents.

And, although you can delete such unnecessary copies manually, specialized applications can save a lot of time.

Especially if the files are located in different folders or in .

You can search for such duplicates using the universal software or designed for specific type data.

In the first case, the search speed increases, in the second, the probability of finding all copies increases.

Universal Applications

Universal Applications to search for copies, they mainly work on the principle of comparing file sizes.

And, since the probability of the same number of bytes in different photos is practically zero, same values are considered a sign of a duplicate.

Sometimes the algorithm involves checking names - also important parameter for searching, especially since the same data in most cases also coincides in name.

The advantages of the programs are the ability to find files of any type with their help and the relatively high speed of operation. Disadvantage: lower detection accuracy.

So, for example, none of these utilities will consider the same file saved with different resolutions to be a duplicate.

1. DupKiller

And among its advantages we can note:

  • ease of setup;
  • setting multiple search criteria;
  • the ability to ignore certain files (with a certain size or creation date, as well as system or hidden ones).

Important: If files with a size of zero are found, they do not have to be deleted. Sometimes this may be information created on another operating system (for example, Linux).

Rice. 4. Optimization program CCleaner systems can also search for duplicate files.

5.AllDup

Among the advantages of another program, AllDup, we can note support for any modern operating system Windows – from XP to 10.

At the same time, the search is also carried out inside hidden folders, and even in the archives.

Although the comparison of information by default occurs by file names, so it is advisable to change the settings immediately.

But during the search process, each duplicate found can be viewed without closing the application.

And if a copy is found, you can not only delete it, but also rename it or move it to another location.

TO additional benefits application applies and completely free work for any period of time.

In addition, the manufacturer also produces portable version in order to search for copies on those computers on which installation of third-party software is prohibited (for example, on a work PC).

6. DupeGuru

One more useful application The one that searches for duplicates with any extension is DupeGuru.

Its only drawback is the lack of new versions for Windows (although updates for MacOS appear regularly).

However, even a relatively outdated utility copes well with its tasks when working in newer operating systems.

With its help, even system files, and the menu is intuitive and in Russian.

It is noteworthy that, in addition to the usual universal option, the manufacturing company has created a utility for searching for files of a certain type.

There is a separate version for images and another for music.

And, if you need to clean your computer not only from documents and system files (which, by the way, need to be deleted very carefully - sometimes it’s even worth leaving an “extra” copy rather than disrupting the system’s functionality), it’s worth downloading these applications as well.

7. Duplicate Cleaner Free

The utility for detecting copies of any file Duplicate Cleaner Free is different the following features:

  • filtering data by extension;
  • Russian interface language;
  • opportunity free use;
  • high speed.

Its disadvantages include minor limitations when searching for images (for this it is recommended to purchase paid version) and not entirely accurate translation of individual menu items.

However, due to its effectiveness and ease of use, the application enjoys some popularity.

Finding duplicate audio files

If the duplicate search results do not satisfy the user, you can consider an option designed for certain files. For example, for accumulated on disk.

This need often arises when downloading several albums and collections of the same artist at once - often the same tracks end up in different folders.

They may have similar sizes and differ in by and large, only by names. Especially for this, there are utilities for searching for similar melodies.

8.Music Duplicate Remover

Among the features of the Music Duplicate Remover program are relatively quick search and good efficiency.

In fact, this application “listens” to the composition and compares it with other audio files.

At the same time, naturally, its operating time is longer than that of universal utilities.

However, the amount of data checked by the program is usually tens of times less, so the average duration of the scan rarely exceeds a couple of hours.

9.Audio Comparer

At the same time, photo analysis also takes longer compared to searching for files of any extension, but the result is worth it.

Images are detected even when there are several duplicates of the same image on the disk, but with different resolutions and, accordingly, sizes.

In addition, to increase efficiency, files with any graphic extensions– from to.png.

This feature distinguishes the utility from most others, to work with which you will have to read help files that are not always correctly translated (and sometimes even provided only in English).

In fact, the application is another version Audio Comparer, and is also distributed under a “shareware” license – that is, the user will have to pay for certain functions.

In this manual about several free and simple ways Find duplicate files on your computer in Windows 10, 8 or 7 and delete them if necessary. First of all, we will talk about programs that allow you to search for duplicate files, but if you are interested in more interesting methods, the instructions also touch on the topic of finding and deleting them from using Windows PowerShell.

Why might this be needed? Almost any user who has enough long time saves archives of photos, videos, music and documents to its disks (no matter internal or external storage), with a high probability that duplicates of the same files are “formed”, occupying extra space on HDD, SSD or other storage device.

Important: I do not recommend searching for and removing (especially automatic) duplicates on everything at once system disk, indicate your custom folders. Otherwise, there is a significant risk of deleting necessary system Windows files, which are needed in more than one copy.

AllDup is a powerful free program for finding duplicate files

Free program AllDup is available in Russian and contains everything necessary functions and settings related to searching for duplicate files on drives and folders in Windows 10 – XP (x86 and x64).

Among other things, it supports searching across multiple disks, inside archives, adding file filters (for example, if you need to find only duplicate photos or music or exclude files by size and other characteristics), saving search profiles and its results.

By default, the program compares files only by their names, which is not very reasonable: I recommend that immediately after starting use you enable the search for duplicates only by content or at least by file name and size (these settings can be changed in “Search method”).

When searching by content, files in the search results are sorted by their size, available preview for some file types, such as photos. To remove unnecessary duplicate files from the disk, mark them and click the button at the top left in the program window (File manager for operations with selected files).

Choose whether to delete them completely or move them to the trash. It is permissible not to delete duplicates, but to transfer them to some separate folder or renaming.

To sum it up: AllDup is a functional and customizable utility for quickly and convenient search duplicate files on the computer and subsequent actions with them, moreover, with a Russian interface language and (at the time of writing the review) free of any third-party software.

You can download AllDup for free from the official website http://www.allsync.de/en_download_alldup.php (there is also portable version, which does not require installation on a computer).

DupeGuru

DupeGuru is another excellent free program for finding duplicate files in Russian. Unfortunately, the developers have recently stopped updating the version for Windows (but update DupeGuru for MacOS and Ubuntu Linux), however, the version for Windows 7 available on the official website http://hardcoded.net/dupeguru (at the bottom of the page) also works perfectly in Windows 10.

All you need to use the program is to add folders to search for duplicates to the list and start scanning. Upon completion, you will see a list of duplicate files found, their location, size and “percentage” of how much this file matches any other file (you can sort the list by any of these values).

For example, in my case, one of the recently tested programs, as it turned out, copied its installation files to the Windows folder and left it there (1, 2), taking away my precious 200-plus MB, the same file remained in the downloads folder.

As you can see in the screenshot, only one of the found samples has a mark for selecting files (and only it can be deleted) - in my case, it is more logical to delete not from Windows folders(there, in theory, the file may be needed), but from the downloads folder. If the selection needs to be changed, mark the files that do not need to be deleted and then, in the right-click menu - “Make selected as standard”, then the selection mark will disappear for the current files and appear for their duplicates.

I think it won’t be difficult for you to figure out the settings and other DupeGuru menu items: they are all in Russian and quite understandable. And the program itself searches for duplicates quickly and reliably (the main thing is not to delete any system files).

Duplicate Cleaner Free

A program for finding duplicate files on a computer Duplicate Cleaner Free is another rather good than bad decision, especially for novice users (in my opinion, this option is easier). Despite the fact that it relatively unobtrusively offers to purchase Pro version and limits some functions, in particular search only identical photos and images (but filters by extensions are available, which also allows you to search only for pictures, and you can search only for the same music).

Just like previous programs, Duplicate Cleaner has a Russian interface language, but some elements appear to have been translated using machine translation. However, almost everything will be clear and, as mentioned above, working with the program will most likely be very simple for a novice user who needs to find and delete identical files on the computer.

You can download Duplicate Cleaner Free from the official website https://www.digitalvolcano.co.uk/dcdownloads.html

How to Find Duplicate Files Using Windows PowerShell

If desired, you can do without third party programs to find and remove duplicate files. I recently wrote about how in PowerShell and this same function can be used to search identical files on disks or in folders.

At the same time, you can find many different implementations of scripts Windows PowerShell to find duplicate files, here are some options (I myself am not an expert in writing such programs):

Below in the screenshot is an example of using a slightly modified (so that it does not delete duplicate files, but displays a list of them) first script in the images folder (where two identical pictures- the same ones I found AllDup program).

If creation is for you PowerShell scripts- a common thing, then I think that in the examples given you will be able to find useful approaches that will help you implement the search for duplicate files in the way you need or even automate the process.

Additional Information

In addition to the above programs for finding duplicate files, there are many other utilities of this kind, many of them are not free or have limited functions until registration. Also, while writing this review, I came across dummy programs (which pretend to be looking for duplicates, but in fact they only offer to install or buy the “main” product) from fairly famous developers that are well-known to everyone.

In my opinion, freely available tools for finding duplicates, especially the first two of this review, are more than sufficient for any search for identical files, including music, photographs and pictures, documents.

If the above options did not seem sufficient to you, when downloading other programs you found (and those I listed too), be careful during installation (to avoid installing potentially unwanted software), or even better - .
