Over time, as files are created, deleted and edited, you hard drive can become fragmented. This means that the various pieces that make up individual files are scattered in various locations across the drive so when the file is accessed, Windows has to spend time piecing together all of the bits before the file can be used. The process of defragmenting a hard drive collates files fragments into contiguous units so that they can be accessed more quickly, helping to improve performance.
While Windows features its own built in defragmentation tool, it can be a little slow and cumbersome to use. O&O Defrag Professional does the same job as any other defragmentation tool in that it will reorganise the files on your hard drive for faster access, but it also goes much further. An in depth analysis of your hard drive will reveal just how often individual files are used, and this information can be used to place them in the optimum position on the hard drive.
Background monitoring means that your drives are constantly monitored for performance hampering fragmentation and defragmentation will take place automatically during idle time. A scheduling option is also available so you can perform deep analysis and maintenance of your hard drive on a regular basis, helping to return the performance of your computer to what it was when it was new.
