Fragmentation is caused by creating and deleting files and folders, installing new software, and downloading files from the Internet. Computers do not necessarily save an entire file or folder in a single space on a disk; they're saved in the first available space. After a large portion of a disk has been used, most of the subsequent files and folders are saved in pieces across the volume.

Hard disks are by far the slowest component in your computer. Therefore fragmented disks often become a bottleneck of the system performance. Besides causing slowdowns, fragmentation makes the disk drive heads move too much when reading files which leads to freeze-ups and system crashes. Auslogics Disk Defrag was designed to remedy system sluggishness and crashes caused by disk fragmentation. It will help you get the maximum performance out of your expensive hardware investments.

With its auto-defragmentation feature, Auslogics Disk Defrag acts in real time, while your system is idle. Since Disk Defrags very compact and requires few system resources, it can easily defragment your hard drives in the background and you will not even notice its activity. Just set Disk Defrag to run automatically and you’ll forget about disks fragmentation shortly. You can also schedule a disk defragmentation process.

Note that this is the Pro version of Disk Defrag 12. The Pro version offers HDD optimisation algorithms, a disk cleanup option, a scheduler so you can setup your defragmention process to start through the night and a 3-PC license.

Please note, Disk Defrag 12 is designed to optimise your hard drives (HDD) and not an solid state drive (SSD).
