The disk maintenance tool used to put file parts back together to increase speed is:

• A. Disk Defragmenter
• B. Disk Cleanup
• C. Disk Formatter
• D. Disk Error Checker

Answer: (A)

Fragmentation happens when a file’s pieces get scattered across the disk. The disk defragmenter rearranges those pieces so the data for each file sits contiguously, which reduces the back-and-forth seeks the read/write head has to make. That improvement in data locality speeds up access and overall disk performance on traditional hard drives. The other tools do different jobs: Disk Cleanup removes temporary and unused files to free space but doesn’t reorganize existing file data; Disk Formatter prepares the drive for use by setting up a filesystem (and typically erasing data); Disk Error Checker looks for and repairs disk errors but doesn’t reorganize file blocks to boost speed.
