DuplicateFinder is a simple Windows utility that can scan your computer, looking for duplicate files. Even if the files have been renamed, DuplicateFinder can still identify them. It has diffent scan modes to detect the duplicated entries. They are Global mode which compares every single file in the specified location, searching for any identical files, specific mode which scans the selected folder; searching only for files that match a user-defined file, and MD5 Checksum mode where DuplicateFinder will search for files that match a user-defined MD5 checksum.
