Free Up Disk Space By Finding And Deleting Duplicate Files In Windows

Are you worried that you might have duplicate files hoarding up hard drive space on your computer? If yes, then do not bother manually searching for those suspected duplicates. Doing so manually can be grossly time-consuming and even inefficient.
One of the best free solutions out there to check for duplicate files is Duper.
Duper is a freeware program that runs in Java; the only requirement is to have Java installed whether you are running Mac OS, Linux, or Windows. Once we add the directories-to-be-searched in Duper, it looks for files with identical file sizes. For each group of files with the same size, an MD5 sum is computed and then used to determine if they are identical.

This second check is what determines whether the files are truly identical or not. The user is then notified of the number of detected identical files.

We can then choose to delete the duplicates or keep them as they were.

The program’s options can be modified before executing any searches to change the level of detection.
Overall, Duper is a great freeware duplicate file detection solution and will serve most users very well.
