I like to extract playlist information (i.e. path and filenames) I've created on Android's builtin MP3-player, to copy it with the MP3 files to a bigger SDHC card. Playlist information is lost when doing this:

• Removing the SDHC memory card (after turning off the device), and re-insert it later, causes the MP3-player to forget all files in the playlists which I have created. This is especially annoying if you want to replace the SDHC card by a bigger one and want to backup all files including playlists from the old one

Hence I am looking for a way to backup the playlists or at least their content (i.e. path filename etc).

More information:

The phone has a playlist folder, containing the Playlists, when I use a USB cable to connect it to the PC, I can see them (*.pla files) but they have 0 bytes and cannot be copied. Also, if I connect the SDHC card via cardreader, the files aren't useful.

Samsung Kies also did not work for me, it does not seem to support the playlists created on the phone.

I found this interesting question, which explains that Android stores playlists in SqlLite databases, but unfortunately, on my Samsung phone I could not find the database file (although there is a folder Computer\GT-I8190\Phone\Android\data\com.google.android.music which should contain it, but no databases subdirectory and no database files).

To summarize my question (one of the options below would help me):

• Do you know how I can backup the playlists on the phone and then extract the file/path info contained in them in Windows?
  Phone Playlist -> Windows PC -> Extract Path/Filename to text file

• Or do you know if there is a tool available (for Android, or for Windows reading it from the mobile phone) converting the playlists into a compatible text format (like .m3u playlists)?
  Phone Playlist -> M3U file
  
  (Note: The other way round it is possible, as this forum post explains). Here's an example of a M3U file, note that relative paths are allowed as well:

  #EXTM3U
#EXTINF:123, Sample artist - Sample title
/storage/extSdCard/Sounds/Sample.mp3

Your help is much appreciated!
