Which of the following applications can be scheduled to delete unwanted, compressed, older files?

Disk Defragmenter reorganizes fragmented file data on a disk to improve read performance but does not delete any files.

Disk Cleanup scans for and removes temporary files, system files, Recycle Bin contents, and compressed older files to free disk space. It can be automated by scheduling it through Task Scheduler using the command 'cleanmgr /sagerun', making it the only tool among the choices that both targets unwanted file categories and supports scheduling.

CHKDSK scans the disk for file system errors and bad sectors and repairs logical file system issues but does not remove or clean up user files.

Disk Management is used to initialize disks, create and format partitions, and assign drive letters - it has no file deletion or scheduling capability.
