Auslogics Disk Defrag is designed specifically for fast optimization of today's modern hard disks. Disk fragmentation leads to system slowdowns, PC crashes, slow startup and shutdown and sometimes to system failures. Hard disks are by far the slowest component of your computer. Therefore fragmented disks often become a bottleneck of the system performance. Besides causing slowdowns, fragmentation makes the hard drive disk heads move frequently when reading files which leads to freeze-ups and system crashes. It is important to keep your disks defragmented and optimized as much as possible.Auslogics Disk Defrag Features: Improve computer performance and stability Increase your productivity - no more waiting for files to open Defragment disks in only a few minutes Useful disk fragmentation map and detailed fragmentation report
