DOSFS bug?

I am getting a “Not found” error with the file “$.Music.0 EXEC_REBIRTHIA=PROTOCOL_/mp3” (original is “\Music\0 EXEC_REBIRTHIA=PROTOCOL_.mp3”).

The original file had " (Ar Tolenico 3)" at the end of the filename, and in RISC OS the file appeared as “EXEC_RE….” (missing the "0 " at the start); I have renamed it once, I’ll rename it s’more. ;-)

While I’m here – I am having trouble figuring out the DigitalCD playlist. If I start the program and drag a directory of songs to it, then it’ll play. Setting up a playlist doesn’t seem to want to work for me. How would I point DigitalCD at a directory of MP3s and have it auto-start playing (pref. randomised but not essential) when I run the program?
