Hi, Russel.

>I would like to populate a list with the drive letters of availble disk drives and shared drives. Is there a way to do this?

Use Windows Script Host:

oFileSys = CreateObject("Scripting.FileSystemObject")

for each oDrive IN oFileSys.Drives
   ? oDrive.DriveLetter
next

Take a look at the other properties of oDrive on Intellisense. They contain useful information.

Hope this helps,
