I think it is useful for making it portable across different plataforms - win32 doesn't have 'find', unless you install cygwin. It is a good exercise for beginners.
You can use File::Find to find files and then File::MimeInfo or File::MMagic to check its file type. If you want to extract some data from images (size, resolution, etc) you could use PerlMagick .
Update: Figured out that File::Info is broken under Windows. File::MMagic worked well in my tests with images, but not with mp3 files.
