SyncServer - Version 2.2 A tool that allows users without administrative privileges to 'sync' the drives on a local or remote computer. This is useful because Windows NT uses aggresive disk-caching schemes to optimize disk access patterns; the trade-off is the risk of file-system corruption if a crash or BSOD occurs. 'Sync'ing a computer's drives every now and then will ensure that already-saved vital data is not lost.
