This is probably something obvious, but I can't seem to find the info
I need with google.

I am fixing an air app that someone wrote. one of the requirements is
that when the client distributes it on cd, the app needs to copy data
files from the cd to the system. these files get changed via a tool
regularly and so would need to be on the cd, but not packaged within
the air app.

I can't figure out how to access the cd drive without using a constant
mapped value which would likely be different on all systems.

Any help would be much appreciated.

Thanks in advance,
Nikki
