Clean up and defragment your hard drive in Windows

SOLVED•by TurboTax•64•Updated December 12, 2023

Your Windows computer will perform more efficiently if you periodically remove unnecessary files from your hard disk and consolidate disk space.

You can use Disk Cleanup and Disk Defragmenter to perform these maintenance tasks.

Disk Cleanup

The Disk Cleanup utility frees up space on your hard disk by finding files you can safely delete. You can decide which files you want to delete.

The method for using the Disk Cleanup utility depends on your version of Windows:

Disk Defragmenter

The Disk Defragmenter utility consolidates files so they occupy space more efficiently. The end result is that files are accessed faster, improving your computer's overall performance.

Defragmenting can take an hour or more, so it's best to do this when you don't need to use your computer.

Select Start, Windows Administrative Tools, and Defragment and Optimize Drives.
Select the hard drive to be defragmented (usually the C drive).
Select the Optimize button. If a User Account Control message appears, select Yes.

If you have multiple hard drives, repeat these steps for each drive.
