O&O Defrag solves the performance and stability problems of Windows workstations and servers caused by fragmented hard disks. Fragmented hard disks put the brakes on the servers in a company and as a result have an adverse affect on productivity. The level of fragmentation proportionally increases the time needed for accessing a hard disk. This in turn increases the amount of valuable time lost by each and every employee. The new O&O Defrag 15 Server Edition for Windows servers optimizes your hard disk and packs file fragments securely back together again.
