❓ Frequently Asked Questions
How does Disk Cleanup differ from Disk Defragmenter?
Disk Cleanup deletes unnecessary files to increase free space, whereas Disk Defragmenter reorganizes existing files on a mechanical hard drive to improve access speeds. One removes data; the other optimizes data placement.
