Virtual Drive SDK allows you to create and manage virtual disks that appear in Windows as regular disks. Virtual disk can be located anywhere: on hard disk, network, random access memory, database etc. Virtual Drive SDK makes possible to implement read/write operations without having to develop your own kernel driver. All necessary part of boring work is done, so you can focus on storage, encryption etc.
Version 1.4 includes bug fixes; multiple VDSDK initialization/deinitialization, VDSDK Stand-alone mode (without installation), additional drive flag; removable drive, VDSDK notification handlers, and other improvements.
