- you can specify a comma-seperated list of file-extensions. Files of this type will not be added to the
    playlist when the directory module parses directory contents.
    This prevents duplication of playlist items (both m3u and the real files were being played, or both .bin and .cue were added, therfore playing the same movie twice) and the adding of items that are not really useful to VLC as seperate playlist items.
  - By default are ignored the following: m3u,nfo,jpg,gif,sfv,txt,sub,idx,srt,cue
