With CallbackDisk you can create and manage virtual disk devices within your application and expose these disks to Windows as if they were real disk devices. The disks become visible to all process in the system. CallbackDisk provides a kernel-mode driver, which calls your application when it needs to perform reading or writing to the disk. And your application can store the actual disk data anywhere it needs: in memory, over the net etc. .
