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.
Warning to those that stumble upon this program! Unfortunately, this program missed 2 important files from 93 test files of duplicates. This was in the importing processes of files from a directory into its own window. I tried every configuration and menu selection and gave the program a thorough test. To miss files is a major flaw. I have un-installed it. All those people who gave this good reviews have never tested it properly. It's never been updated from the first Beta over 4 years ago and should be removed from this site.
Not a good software if you choose to use on large list of files. This will not helpful for me where I deal with lot of duplicate files.
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.
