Disk Defragmenter (Simulator)

Fragmentation: 0%

Status

Analysis complete. Disk is fragmented for demonstration.
This tool simulates how a defragmenter rearranges file blocks (clusters) so that each file is stored in one continuous run. This reduces the amount the hard-disk head has to move, which speeds up reading large files.

GCSE tip: on a traditional hard disk, fragmentation matters because the read/write head has to keep jumping around. After defrag, the head can read big files in one smooth sweep. (You do not defrag SSDs.)
