FYI, illegal characters in Windows are :

\ / : * ? " < >

I guess I knew that somewhere in the dark recesses of my brain. I just chose not to remember it.

I also would avoid % and most of the extended characters, such as the directional typographer's quotes.

This is probably a good idea. Unfortunately I'm using a Mac application (SoundJam MP) that generates the file names from the song titles. (Hmm - I wonder if there are any options to have it avoid certain filename characters.) Otherwise I'll just have to keep an eye out and change the file names once they're created.

Thanks...
