Can some one tell me the folder where gmusicbrowser save playlist?
so i can copy all of them in another folder..

Thanks !

Currently the playlists are saved with everything else in the file ~/.config/gmusicbrowser/gmbrc  (~/.config/gmusicbrowser/tags for v1.0.x) as a list of numbers.
I may add a way to save them as playlist files in the future.
If you want to export your playlists you can currently with the export plugin select songs and choose to export them to a m3u file. I'll add a way to export all named playlist.

Ok! Thank you very much for your fast answer..!
