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…

Question

Options

• ADisk defragmentation
• Bchkdsk command
• Cfdisk command
• DDisk cleanup

• A
  88% (22)
• B
  4% (1)
• C
  8% (2)

Explanation

Disk defragmentation is correct because when files are deleted from a traditional HDD, the remaining files become scattered (fragmented) across non-contiguous sectors. Deleting many files worsens this fragmentation, forcing the read/write head to physically travel farther to access file pieces - directly causing the slow open/save times Ron experiences. Defragmentation reorganizes those scattered file chunks into contiguous blocks, dramatically improving read/write speed.

• B (chkdsk) scans for and repairs file system errors and bad sectors - it addresses corruption, not performance slowdowns from fragmentation.
• C (fdisk) is a disk partitioning tool used to create, delete, or resize partitions - not relevant to performance or file fragmentation at all.
• D (Disk Cleanup) frees up space by removing temporary files and system junk - useful before this problem, but it doesn't fix the slowness caused by fragmentation that already exists.

Memory tip: Think of fragmentation like a book with its chapters scattered across different shelves in a library. Defrag "reshelves" the chapters together so you don't have to run around to read them - and Ron's slow drive is exactly that library after a chaotic cleanup.
