I am trying to cleanup my mp3 collection and I have a bunch of songs that have the artist at the beginning of the song or numbers so I wanted to know if there is a way take the number from the filename and put it into the details (track number) of the file. I already know how to read files from folders I am just not sure how to change the details of a file if possible.
Have you considered using Mp3Tag it's a very nice application that actually has tools for analyzing file names and putting the details in to the tags.
