Over time, due to copy-pasting errors, multiple downloads, etc, a computer tends to accumulate duplicate files. This means that you have multiple copies of files taking up space on your disks. A Duplicate File Finder software, using a binary search algorithm, is able to find and list out these duplicate files, enabling you to delete the extras and free up more space. Not only do you free up space, you also avoid the confusion that may be caused due to the existence of multiple copies of the same file. There are many software available for free on the internet that fall under this category of Duplicate File Finder software.

Once the files have been detected, one can delete them, move them to another particular folder, export a list of files, etc.
