HamMultiPlayer is a software created to scan your directories (and/or drives) to find and display several files in real-time. It can be used to find, move, delete, or preview any video/audio file. This is a "portable" software, this means that everything is already included inside the ".exe" (no installation, no registry keys, ...). It uses MPlayer (32/64bits versions) and MediaInfo Library to decode and display files (so it can play everything Mplayer can play).
The program size is very small: 32 MBytes.
HamMultiPlayer scans recursively directories you selected and load any compatible file. You can then, sort the generated list to find out duplicated or similar files.
HamMultiPlayer works with Windows XP, Vista, 7,8, and 10 in both 32/64bits architectures. This program was compiled in 32bits and includes both 32/64bits players to decode any file.
HamMultiPlayer is the program I have been looking for for years until I decided to do it myself. I don't guaranty anything. Use it at your own risk!
