Podcast and Radioplaylist editing

Hello People,
i have found this nice piece of software (0.6) for my RP1 and its really nice so far :). I have a lot of Podcasts in an opml and Radiostations that i want to add but it would be a pain to add them all by hand. I am looking for the path to the playlist locations on the SD-Card but i cant find it. I cant be the first that want to add playlists like that, or am i? Because i couldnt find anything related by search in this forum :confused:

So, can someone help me please? I cant find the files :frowning:
