Re: Searching for paths
For finding what drives are on a system, Al Getz has some code in the
archives:
http://www.rapideuphoria.com/getdrive.zip
it's written as a windows program, but the drive functions can easily be
abstracted; it gives *all* drives on system, but you can also easily make
it just return hard disk drives.
Does say "--requires Windows 95 OEM Service Release 2 (OSR2) or above.", so
it might not work on all systems?
