DOS kernels only assign driveletters to FAT filesystems. For (emulated?) floppy drives A: and B: get assigned, thus C: till Z: get assigned to everything else. A FAT filesystem contains the NUL blockdevice, making it easy to test: @echo off IF EXIST C:\NUL echo Driveletter C: points to a FAT filesystem. Testing if you can store files on the drive is a different issue altogether, as it involves: * checking if the drive isn't full yet * checking if the drive isn't write-protected (read-only) * checking if there's enough free diskspace Bernd ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.
