Bruce,
Thank you for replying. I decided to go with DiskFreeSpace of Setupkit.dll (solution that I also found in the MS support FAQ section for VB). This approach seems to be simpler than API's GetDiskFreeSpace, which I have to admit I didn't use because of the slew of parameters required (sector size, number of clusters, etc) that made it look complicated.

>>Is there a function in VB (3.0 and above) that would return the available disk space?
