Ron has an older computer to which he frequently downloads and saves company files. He recently noticed that he was running low on disk space and decided to delete many old files that he no longer…

• ADisk defragmentation

• Cfdisk command
• DDisk cleanup

Explanation

Disk defragmentation (A) is correct because deleting many files leaves fragmented free space scattered across the disk - when new files are saved or existing ones grow, they get split into non-contiguous fragments, forcing the read/write head to seek multiple locations and slowing performance. Defragmentation reorganizes those fragments back into contiguous blocks, restoring normal speed.

chkdsk (B) scans for and repairs file system errors and bad sectors - it addresses corruption, not fragmentation-related slowness. fdisk (C) is a partitioning tool used to create, delete, or resize disk partitions; it has nothing to do with file access performance. Disk cleanup (D) frees space by deleting temporary files and system junk - Ron already did the equivalent of this manually, and it wouldn't address the read/write slowness caused by fragmentation.

Memory tip: Think "defrag = defragment = put the puzzle pieces back together." Deleting files creates gaps (fragments), and defrag fills those gaps - if performance slows after deleting files, defrag is the fix.
