Thanks Mac. I'm keeping my BIAB files on my desktop.

I just looked inside the folder and found .sgu and .mgu and .mgx files and have no idea what the extensions mean, but I'm still at the "playing around with it" stage.

I did pull up a file yesterday and nothing was inside (nothing!) even though it had a name, so I have no idea what happened but fortunately, the previous "save" worked. Naming them song1a song1b etc. helps -- at least so far, but obviously won't in the future.

Thanks
Debb
