At a particular point of time, the files in your system tend to get scattered on the disk, thus increasing the execution time of the respective program. The disk defragmentation utility in Windows can thus scan for and rearrange these scattered files on your hard drive.
Usually defragmentation is required once every week. But at times it may not be possible to remember performing a scan especially if you’re on a tight schedule. You can thus schedule the defragmentation utility to run as and when required.
