Defragmentation
Download as PPTX, PDF2 likes2,051 views
Fragmentation occurs over time as files are saved, changed, and deleted, storing file data in different locations on a volume. This causes hard disks and removable drives like USBs to work less efficiently. Disk Defragmenter rearranges fragmented data to improve efficiency. It can run automatically on a schedule or be used manually to analyze and defragment drives. Defragmentation consolidates fragmented files so the drive works faster by reducing read/write head movement.
