Dennis,

Fp, in the days of smaller drives, allowed for adding key/data extents to the same or different drives.  Today with the larger drive capacity, the only time one would want to do this is when the file size is nearing the 2GB limit on a 32bit OS.

I don't recall exactly what the naming convention is for these extents.  

To add an extent
1.run expand files
2. select the file wanted
3. At the prompt for the number of records to add, type <switch>.  This will list the available drive to store the extent.  
4. Select a drive to store the extent on

I tested this on my system and found that no extent was added on my hard drive.  I am not sure if fp checks to see if the file size requires an extent before adding one if the request is to the same drive.  Someone more familiar with extents may be able to answer that question.
