For more information, check out our FSDK Data Sheet. Windows NT 4.0 Volume Manipulation Developers Kit (VMDK) With the OSR VMDK you can very easily discover and manipulate the clusters that comprise a file on an NTFS or FAT volume. Do not confuse this kit with a simple facility that lets you move a cluster of a file to an unspecified "contiguous" location! Implemting far more than just a couple of clever IOCTLs, the OSR VMDK allows you to specify which clusters of a file to move, and which clusters on the volume you want them moved to. You thus have control of the resulting volume layout. Of course, this kit works on-line, during normal system operation. Cool for writing defraggers, volume mappers, and other neat utilities. This kit is scheduled for availability during the first quarter of 1997. Contact OSR (info@osr.com) for full details.
