A technician notices that a Windows 10 laptop with a traditional spinning hard drive is taking noticeably longer to load applications and open large files. To improve read/write performance by rearranging fragmented data on the disk, which built-in command-line utility should the technician run?
DEFRAG
DISKPART
CHKDSK
FORMAT
The Defrag utility (defrag.exe) analyzes the drive, locates fragmented file blocks and rewrites them so that each file occupies contiguous sectors. This consolidation reduces seek time on mechanical hard-disk drives, resulting in faster file access. Solid-state drives do not benefit from defragmentation and are instead automatically optimized via TRIM commands.
