One way could be to define a list of file extensions that
commonly matches the content you want to track. Of course,
the file name does not directly correspond to the content,
but it often gives a good hint to search for *.wmv, *.flv,
*.avi, *.mp(e)g, *.mp3, *.wma, *.exe - and of course all
the variations of the extensions with uppercase letters.
Also consider *.rar and maybe *.zip for compressed content.

If file extensions have been manipulated (rare case), the
"file" command can still identify the correct file type.
