Defragmenting your hard disk (often called defragging) is a process in which the data on a hard drive is re-arranged in to a logical order, where single files and directories are ordered next to each other on the disk to improve read speeds on mechanical hard drives.

A good defragging application may be able to speed up your system, especially if this process has never been performed before. Although NTFS and Windows 7 are optimised to reduce drive fragmentation, it is worth performing a defrag occasionally to keep your system at its best possible performance.

Depending on the fragmentation level and size of your drives, it could take anywhere from a few minutes to over an hour to complete.
