The INI-file is compatible with most previously saved files and may be
compatible with future QuickPlayer versions. Some settings, of course, may be
ignored when using different versions.

The playlist (m3u-file) is compatible, but when using QuickPlayer playlists with
other players / other QuickPlayer versions (or versewise), only the playlist
itself (filelist) will be loaded. Any additional settings will get lost.

Preset files (*.qps) are similar to the INI-file. Use them to quickly changes
multiple settings at once. You can use up to 64 presets. You can use the
built-in preset manager or create presets with a simple editor. You can also
copy and rename your current INI-file (if QuickPlayer is running, save settings
first).

The following settings are stored in the playlist (m3u):
 - Autorefresh refresh interval (#AutoRefreshTimer)
 - Autorefresh directories (#AutoDir=...)
 - Current/next song (URL) / position (mostly ignored) (#CurrentSong,
   #CurrentSongPos, #CurrentURL, #NextSong)
 - Playlist (non-refresh songs only) (x:\...\*.*; #Dir=x:\...)
