This article discussed programs with which you can quickly and easily extra effort detect duplicate photos on your hard drive and delete them permanently. Let everyone decide for themselves which tool to use, but it’s worth knowing that any of them will 100% cope with the task.
Sometimes in everyday life computer activities The task arises of finding duplicate files. There can be many reasons for this: lack of space on the hard drive, attempts to reduce entropy in your files, deal with those dumped in different time photographs from the camera and many other necessary cases.
You can find a large number of programs on the Internet that allow you to search for duplicate files. But why look for any programs if a smart tool for such work is usually always at hand. And this tool is called Total Commander (TC).
In this article I will show all the methods based on Total Commander versions 8.5 , in this version, the search for duplicate files has become very rich in functionality.
!!!A small important digression. What do you mean by duplicate file? Two files are IDENTICAL only if they are exactly the same bit by bit. Those. Any information in a computer is represented by a sequence of zeros and ones. So, files match only when they completely match the sequence of zeros and ones that make up these files. All talk about how you can compare two files on any other basis is deeply erroneous.
TC has two, essentially different, methods for finding duplicate files:
- Synchronize directories;
- Search for duplicates;
Their features and application are best illustrated with examples.
1.Directory synchronization.
This method is used when the two folders you are comparing have an identical structure. This usually happens in many cases, here are a few of them:
- Have you regularly archived your work folder? After some time, you need to find out which files have been added or changed since the archive was created. You unpack the entire archive into a separate folder. The folder structure in it practically coincides with the working one. You compare two folders “original” and “restored from archive” and easily get a list of all changed, added or deleted files. A couple of simple manipulations - and you will remove from the recovered folder all the duplicate files that are in the working one.
- You are working in a folder on network drive and regularly make a copy to yourself local disk. In time your work folder has become quite large and the time spent on full copy, has become very large. In order not to copy the entire folder each time, you can first compare it with the backup one and copy only those files that have been changed or added, and also delete them in backup folder files that were deleted from the main one.
Once you get the hang of it and feel the full power of this method, you yourself will be able to come up with thousands of situations where the directory synchronization method will be of great help to you in your work.
So, how does everything happen in practice? Let's get started.
Let's assume we have a main folder "Working", which contains the files with which you are working. And there is a folder "Archive", in which lies old copy folders "Working". Our task is to find duplicate files in both folders and remove them from the folder "Archive".
Open TC. In the right and left panels, open the folders being compared:
Press menu “Commands” - “Synchronize directories...”
The directory comparison window opens 
Next we need to set the comparison parameters. Put a tick in the parameters “with subdirectories”, “by content”, “ignore date”
- "with subdirectories"— files in all subdirectories of the specified folders will be compared;
- "by content"- Here key option, which forces TC to compare files BIT by BIT!!! Otherwise, files will be compared by name, size, date;
- "ignore date"- this option forces TC to show differing files without trying automatic detection directions for future copying;
!!! Files will only be compared with same names!!! If the files are identical, but they have different name, then they will not be compared!
Press the button "Compare". Depending on the size of the files, the comparison can take a very long time, do not be alarmed. Eventually the comparison will end and the result will be displayed in the bottom status line (section 1 in the figure): 
If the buttons in the “Show” section (section 2 in the figure) are pressed, then you will see the comparison result for each file.
— this button enables the display of files that are in the left panel, but not in the right;
— this button enables the display of identical files;
— this button enables the display of differing files;
— this button enables the display of files that are in the right panel, but not in the left;
If you initially have all display buttons turned off, then the result of the comparison can only be assessed by the status bar (section 1 in the figure above), in in this case we see that 11 files were compared, of which 8 files are the same, 2 files are different, and there is also a file in the left panel that is not in the right panel.
To complete our task, it is necessary to leave the display of only identical (identical) files, so we turn off all other display buttons 
Now we only have identical files left, and we can safely delete them in the folder "Archive". To do this, select all files. The easiest way to do this is by pressing the universal combination CTRL+A. Or first select the first line with the mouse, then press the key on the keyboard SHIFT and without releasing it, select the last line with the mouse. As a result, you should get something like this: 
The final step is to click right key mouse on any line and select the item in the menu that opens "Delete on the left"
TC kindly asks us about our desire, 
and if we press "YES" then it deletes all marked files in the folder "Archive".
After this, the two folders are automatically compared again. If you do not need a repeated comparison, the process can be interrupted by clicking on the button "Abort" or press a key ESC on keyboard. If the repeated comparison was not interrupted, and we turned on all the display buttons, then we will see a window like this 
All. The task has been completed. All identical files found and deleted in the folder "Archive".

2.Search for duplicates.
Fundamental difference this method from the directory synchronization method is that TC ignores the names of the files being compared. In fact, it compares each file with each, and shows us identical files no matter what they are called ! This search is very convenient when you do not know either the folder structure or the names of the files being compared. In any case, after searching for duplicates, you will receive an exact list of identical files.
I will show you the search for duplicates on one practical problem, searching for duplicates personal photos. Quite often you download photos from your digital gadgets to your computer. Often the situation gets confused, something is reset many times, something is skipped. How to quickly delete files that have been dropped multiple times? Very simple!
Let's get started.
Let's say you always dump all your photos into a folder "PHOTO" on drive D. After all the resets, the folder looks something like this: 
As you can see, some files are located in folders named by the date of shooting, some are dropped to the root of the folder "_New" And "_New1"
To start searching for duplicates, open the folder in which we will search in any TC panel. In our case this is the folder "PHOTO"
Next, press the key combination on the keyboard ALT+F7 or select from the menu “Commands” - “Search for files”
A window opens standard search TC. String "Search files:" leave it empty, then all files will be compared. 
Then go to the bookmark "Additionally" and check the boxes “Search for duplicates:”, “by size”, “by content” and press "To start searching".
The search can take a VERY long time, do not be afraid of this, as it happens great amount comparisons of large volumes of files. At the same time, the progress percentage is shown in the status bar 
When the search ends, a search results window will open, in which we press the button "Files to panel"
In the search window and in the panel window, identical files are collected in sections separated by dotted lines 
Each section displays the file name and full path to the file. The names of IDENTICAL files can be completely different!
In this case, it is clear that the same photograph was recorded THREE times, twice under the same name( IMG_4187.JPG) and the third time this photograph was recorded under a completely different name ( IMG_4187_13.JPG).
Next, it remains to select unnecessary identical files and delete them. This can be done manually by selecting each file by pressing a key Ins. But it takes a long time and is not effective. There are better and faster ways.
So our task is to remove duplicate files in folders "_New" And "_New1".
To do this, click on additional keyboard, on right big key [+]
. Typically, using this key in TC, files are selected by mask. The same operation can be done through the menu “Selection” - “Select group”
Hello Dear Friend.
When working with files and documents, we quite often do backups important data. In one folder in another in a third... And then we even forget how many copies of this or that file we made and where on the disk they are stored.
As a result, free disk space eaten away by unnecessary copies of files and folders. How can you find duplicate files on all your drives and delete them?
It's very simple, we'll use a small free utility with Russian language support – Soft4Boost Dup File Finder .
You can download the program here:
After installing the program, the main window will open:
If we check the box next to “Ignore file names,” then the search will not use matching file names, the search will be based on the internal contents of the file. This is very important, because identical files can have different names. Fortunately, all the tips in the program are in Russian.
Just below you can select the type of files to search for duplicates.
Choose necessary disks or individual folders (by clicking on the plus signs). Then you need to click on the folder image with the right arrow to add desired list folders to be scanned by the program.
In this window, select the method for deleting files. The first option is added to the trash can with the option of recovery. Please remember that the basket size is limited. To increase the size of the recycle bin, go to the properties of the recycle bin icon on the desktop and set the size in megabytes.
You can also choose the permanent option, but I recommend deleting to trash first. If something goes wrong, you can always restore the file.
Click the “Search” button.
After the scanning is completed, a window with duplicate files found will open in front of you.
Select the checkboxes of the files that you want to delete and click on the button at the top of the “Fix problems” window; the selected duplicates will be deleted.
Like this in a simple way you can get rid of numerous duplicate files on your disks.
Among the disadvantages of the program, I would note the inability to view found files by clicking double click mice. It would be very convenient to immediately view the file and remember what kind of file it is.
