>I have a DBF file that I want to input to a current table in my VFP application. The data will be on a CD-ROM. Each site might have their CD-ROM mapped to a different drive. When the user inserts the CD, how do I find out where the data is, without user intervention, so I can import the data into my table.

Look at the DriveType() function. That will allow you to determine which drive is the CD ROM.
