Mass MP3 Summary editing.

[MonsterAar]

What I want to do is write a program that will take two inputs from the user: a folder (eg. C:\Documents and Settings\Owner\My Documents\My Music\MP3) and a string (eg. "Don't steal music!") and change the summaries of every MP3 in that folder (including in sub-directories) and change the 'Comments' field to the input string.

To be honest I have no idea where to start. I'm not sure how MP3s store summary data or how to achieve this sort of mass editing.

Anyone that could help me get started?

MP3::Tag might be what you're looking for:

As for reading the directories, make a recursive subroutine using opendir, readdir, and closedir.. quick pseudocode

sub scan {
   get $dir from @_
   opendir $dir
   foreach $file readdir $dir
      if $file is a folder
         scan "$dir/$file"
      else
         do something with "$dir/$file"
   closedir $dir
}
