Duplicate Files Finder is a cross-platform application for finding and removing duplicate files by deleting, creating hardlinks or creating symbolic links. A special algorithm minimizes the amount of data read from disk, so the program is very fast.
Just used this one.But DuplicateFilesDeleter is the one that I like most. It is a simple to use, but very effective tool to locate duplicate files in one or more selected search paths.It scans the files and compares them based on Byte for Byte Comparison, which ensures 100% accuracy. You can then choose to delete the selected duplicate or original files. The program is multi-threaded which enhances the performance immensely & performs scans very quickly.
The program is great in theory. However i'm now deleting 2+ million duplicate files manually. It will take a few more weeks and this can't be automated by autohotkey.
