You can place .m3u files anywhere on sdcard which is under reach of media scanner. Playlist will be displayed in music player once media scanner will complete scanning sdcard.

Path of system-created playlists (playlists are common to all music players): /data/data/com.android.providers.media/databases/external-xxxxxxx.db where xxxxxxxx are random numbers. Path can be slightly different based on Android versions &amp; devices.

If you want to backup your playlists, i'd recommend you to use Titanium Backup.
