This is the Virtvol sample driver. This version of the driver has been modified to support the driver frameworks. This driver basically creates a nonpaged pool and exposes that as a storage media. User can find the device in the disk manager and format the media to use as FAT or NTFS volume. In addition, Virtvol integrates with Mount Manager, so that it is not necessary for you to assign a drive letter, the system will do this automatically.
