What is the role of Disk Cleanup and Disk Defragmenter in Windows?

Disk Cleanup is a utility in Windows that helps free up space on a hard drive by removing unnecessary files, such as temporary files, system cache, and old backups. Disk Defragmenter, on the other hand, reorganizes fragmented data on the disk to improve read and write efficiency, enhancing overall system performance. Together, these tools help maintain optimal disk health and speed up system operations. Regular use of both can lead to a smoother and more efficient computing experience.
