Users in an office routinely work with large graphics files. Which of the following preventive maintenance tools can assist in maintaining system performance?

FPROT is an antivirus application used to detect malware, not a tool for improving disk read/write performance.

DEFRAG reorganizes fragmented file data on a hard drive so that large files are stored in contiguous sectors, reducing head seek time and improving read/write speeds. Systems that frequently create and modify large graphics files accumulate heavy fragmentation, making regular defragmentation critical for sustained performance.

CHKDSK scans for and repairs file system errors and bad sectors, but does not address file fragmentation or improve performance for large file access.

SFC (System File Checker) scans and restores corrupted Windows system files and has no effect on disk fragmentation or graphics file performance.
