I have plenty of space on my desktop PC, but limited space on my laptop, and I work with a colleague who brings his laptop to gigs, but doesn't have all the RealTracks that I have.

I've tried inspecting the C:\BB\RealTracks folders, but there doesn't seem to be a way of working out from the folder names or the file names which set they've come from, and particularly whether the whole set has been installed. I sometimes have to delete RealTracks to make space, and it's hard to know which ones to delete.

I thought I might find out what had been installed through Start->Control Panel->Add/Remove Programs, but the RealTracks don't seem to have been installed in the sense that programs are installed, and there is no reference to them in the list of programs that can be uninstalled.

My colleague and I collaborate on arrangements of songs, and exchange completed versions.

What I'd like to have is:

a) A tool which could say quickly which RealTracks are available on a computer

b) A tool which could check a BIAB song file, and say what RealTracks are needed to play it back

c) A tool which could check a BIAB song file, or a folder of BIAB song files, and report on whether any of the files can't be played back on the computer they're currently stored on, or to list all of the songs with a pass/fail comment.

Of course, what we'd really like is

(d) for each of us to be able to check songs we've arranged on BIAB to be sure that they'll work on his colleague's computer before e-mailing them, and avoid the need for the recipient to load them up and listen to them all the way through.
