Which tool removes unnecessary and temporary files?

• A. Disk Cleanup
• B. File Management
• C. Rename a Folder
• D. Save a File in USB Drive

Answer: (A)

Deleting unused and temporary files frees up disk space and can help your computer run more smoothly. Disk Cleanup is the tool designed for this purpose: it scans the drive to find items that are safe to remove and lets you delete them, such as temporary files created by apps, cached browser data, Recycle Bin contents, and even certain old system files. This targeted cleanup is what makes it the best choice for removing unnecessary files.

Other options don’t fit this task. A general “File Management” idea isn’t a specific cleanup tool, so it won’t automatically find and remove temporary files. Renaming a folder changes its name but does not delete any extra or temporary data. Saving a file to a USB drive simply moves data off the computer and does not clean up the system’s unused files.
