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.
program started and froze. turned computer on and off. Same thing. not good
This would be an excellent program if it weren't because you need to select files manually, if you need to compare large set of files forget this program.
