Fragmentation occurs when you make changes to your files by saving, changing, and deleting them. Files are not stored in organized and contiguous spaces on your hard disk. Instead, they are often spread around the disk in fragments. Your PC's performance slows down as your hard disk becomes fragmented.
FULL-DISKfighter is a disk defragmentation tool that will have your disk running faster and more efficiently. Defragging assembles the scattered parts of a file and stores them neatly in one complete piece in a cleared space. This is done with each and every file until the entire disk is defragmented - significantly improving your PC's performance.
