About
Searches through all files in a directory and finds which are MP3-files then moves them to selected folder.

This becomes useful when pointed to the cache-folder of your web browser, for finding MP3′s you have been listening to online using various flash players (llike Grooveshark for example)

This is done by reading the header of each file, a MP3-file starts with “ID3″ (hex 49 44 33).

Instructions

  • Start mp3finder.exe (if using Vista/Windows 7, right-click and “Run as administrator”)
  • Click “in directory” or fill the textbox next to it with the path to read from
  • Click “out directory” or fill the textbox next to it with the path to save to
  • Click “Start”!
  • Just wait.. it can take some minutes, depending on size and number of files
