AllDup is a free software for finding and deleting duplicate files including mp3 music files, jpeg/jpg digital photo files as well as video/movie files, it is specifically optimized for mp3 files and jpeg files.
AllDup has a beautiful user interface, but is not well designed. If you do not want to scan the whole partition, you should press the “Add” button under the “Source Folders” tab and choose your own folder, then uncheck the drives which is checked by default.
If you checked the “Content( byte by byte compare )” option under the “Search Criteria” tab, AllDup will allows you choose to first compare a data block at the file end, thus it will not continue comparing two files which have a different small block, it will significantly improve the speed of comparing. If two files have the same content, they have the same MD5 / SHA-1 checknum value.
