Question

briefly describe the disk defragmenter program​

Answer 1

Answer=Disk Defragmenter is a utility in Microsoft Windows designed to increase access speed by rearranging files stored on a disk to occupy contiguous storage locations, a technique called defragmentation. Defragmenting a disk minimizes head travel, which reduces the time it takes to read files from and write files to the disk.[1] Beginning with Windows XP, Disk Defragmenter also reduces system startup times.
