Defragmentation is the process of rewriting non-contiguous parts of a file to contiguous sectors on a disk for the purpose of increasing data access and retrieval speeds. Because FAT and NTFS disks can deteriorate and become badly fragmented over time, defragmentation is vital for optimal system performance. We recommend downloading Auslogics BoostSpeed to explore the multiple ways you can get better performance out of your system without expensive hardware updates.
