DeviceLock - Version 4.1.03 Gives network administrators control over which users can access what devices (ports, floppies, Magneto-Optical disks, etc.) on a local computer. Once DeviceLock is installed, administrators can assign permissions to LPT ports, DVDs, CD-ROMs, COM ports or any other device, just as they would to share-permissions on a hard disk. Network administrators can use DeviceLock to flush a storage device's buffers (very useful for removable media) and to get extended information about devices and NTFS partitions.
