How to Increase Free Space in Local Disk C

by J.S. Copper

The C: drive is the hard drive partition that contains all Windows system files. This includes the operating system files, settings, applications and your documents. As you add and download files to the computer, the space on the C: drive will start to fill up. When you start running out of space, Windows will warn you about the limited available space. There is a utility included in Windows to help clear out unnecessary and/or temporary files to help free up space.

Open the Windows Start menu and type "disk cleanup" into the Search box to launch the "Disk Cleanup" utility.

Select the C: drive from the "Drives" drop-down menu.

Select all file types and click "OK." Windows will scan the computer for the unnecessary files.

Select "Delete Files" after the scan completes. The window will list the amount of space that will be freed up upon deletion.

Drag and drop unnecessary files to the "Recycle Bin" on the desktop. Right-click the Recycle Bin and select "Empty" to delete the files and clear up disk space.


  • check You can also uninstall unnecessary applications via the Control Panel (in the Start menu). Removing applications you no longer use will help clear up space on the C: drive.
