If we are somewhat careless, it is likely that we have on the computer a few duplicate files, where songs or photographs are often highlighted. Having a discomforting hard drive means that it costs us more to find certain files. In addition, if we have limited space to use an SSD we can earn a few hundred MB eliminating duplicate files. For this reason, we are going to make a compilation of the 5 best programs to eliminate duplicate files in Windows, being able to filter them by name, size, date of modification, etc.
AllDup – deletes duplicate files as fast as possible
AllDup has one of the fastest search algorithms, being able to scan hundreds of GB in less than a minute. Lets you export listed to CSV or TXT.

CloneSpy: deletes file even from 0 bytes
This program is one of the easiest to remove duplicate files. It allows finding identical files and those that differ in a slight percentage in characteristics like name, size or date of creation. This helps to remove old versions of the same file that we have, such as a text document, and thus preserve the most complete and recent. It also allows you to find files whose length is zero bytes.
Duplicate Cleaner: the most complete
Duplicate Cleaner is one of the complete programs to remove duplicate files. We can compare files by name, size, date or type, even if the files are not the same, and you can retouch the degree of similarity. It is one of the most complete of the compilation, so, if you are looking for a program of this style installed for a long time on your PC, it is an option that you can consider.
Anti-Twin: Choose what to do with duplicates
Anti-Twin allows you to delete duplicate files and choose whether to send them to the recycle bin for review or delete them directly. It is a good tool especially for comparing photographs since it allows previewing them within the same program. In addition, it allows comparing the photos by the pixels themselves, not just by size or name.
DoubleKiller: No installation
DoubleKiller is a very interesting option if you want to use it once and then erase it, since the program is portable and does not require installation. Thanks to this, the program does not leave any residual files on the PC after using it. Despite having an old interface, the program is quite complete. It allows searching and comparing files by name, format, size, date, or by checksums. It also allows you to exclude certain files from the selections.
If you know another file comparator in addition to the ones we mentioned, do not hesitate to leave it in the comments.
