I answered this question a while ago:
Rockbox playlists are not "ROCKBOX" playlists, they are just "STANDARD" playlists...
SO: you've found a program called "playlist creator"...
Ask on THEIR forum?
- This is NOT A ROCKBOX QUESTION.
- There are THOUSANDS OF OPTIONS.
- GOOGLE IS YOUR BEST FRIEND.
- I personally use the "vi" program. (That response was judged to be "not incorrect", but "not a helpful answer").
- These are just TEXT FILES.
- It is possible that your analog of "vi" might be called "notepad".
- MOST music player programs on MOST platforms can also manipulate playlists.
If you can read and believe everything I just said, you'll be well on your way to finding an approach that works for you...
Note, I think the playlist format was originally invented by the WinAmp program? I could be wrong about that.
Here is a good STARTING point:
http://en.wikipedia.org/wiki/M3UFrom what I've seen, you should start by understanding what an M3U file is, using "notepad"...
That understanding will help GREATLY to use a utility like "playlist creator" (whatever that is)...
