Steps to Increase C Drive Space in Windows 11

First, let’s make more space on your C drive. We’ll take you through deleting junk files and extending your C drive using built-in Windows 11 tools.

Step 1: Delete Unnecessary Files

Open "Storage settings" from the Start menu by typing "Storage" and selecting it.

Once in Storage settings, you’ll see a breakdown of what’s taking up space. Click on "Temporary files" and delete these to free up some space.

Step 2: Uninstall Unneeded Programs

Go to "Apps & features" in Settings by typing it into the Start menu search bar.

Scroll through the list and uninstall programs you no longer need. This can free up a surprising amount of space.

Step 3: Use Disk Cleanup

Open "Disk Cleanup" by typing it into the Start menu and select your C drive.

Disk Cleanup will scan your drive for unnecessary files, like old system files and recycle bin contents. Select the items you want to delete and click "OK".

Step 4: Use Storage Sense

Enable "Storage Sense" from Storage settings to automatically delete temporary files and free up space regularly.

This feature automatically clears out temporary files, which helps in maintaining free space on your C drive.

Step 5: Extend Your C Drive

Open "Disk Management" by right-clicking the Start menu and selecting it.

If you have unallocated space next to your C drive, right-click the C drive and select "Extend Volume". Follow the wizard to complete the process.

After completing these steps, you’ll notice that your C drive has more space, making your system run smoother.
