How to Delete Temporary Files in Windows 11: A Complete Step-by-Step Guide

Over time, temporary files build up on your system and take up valuable storage space. These files are usually created by apps, system updates, and background processes. While some are necessary temporarily, most can be safely removed to speed up your PC and reclaim disk space. If you’re wondering how to delete temporary files in Windows 11, this guide will walk you through every effective method.

Why You Should Delete Temporary Files in Windows 11

Deleting temporary files helps:

• Free up disk space

• Improve system performance

• Fix bugs caused by outdated or corrupted cache files

• Optimize software behavior

• Keep your PC clean and running efficiently

Windows 11 includes several built-in tools to help you safely remove temporary files.

What Are Temporary Files?

Temporary files include:

• Windows Update leftovers

• App cache

• Web browser cache

• Log files

• System error reports

• Old installation files

These files are safe to delete once they’ve served their purpose.

Method 1: Delete Temporary Files via Windows Settings

This is the easiest way to delete temp files in Windows 11:

1. Click the Start menu and open Settings

2. Go to System > Storage

3. Wait a few seconds while Windows scans your storage

4. Click on Temporary files

5. Review the list and check boxes next to the items you want to remove (like:
   • Delivery Optimization Files

   • Recycle Bin

   • Temporary Files

   • Thumbnails

   • Windows Update Cleanup)

6. Click Remove files at the top

This is the safest way to clean up without affecting important system functions.

Method 2: Delete Temp Files Using Disk Cleanup Tool

The classic Disk Cleanup tool still works in Windows 11:

1. Press Windows + S and type Disk Cleanup, then select the app

2. Choose your system drive (usually C:) and click OK

3. The tool will scan for temporary files

4. Check the boxes next to categories like:
   • Temporary Internet Files

   • Delivery Optimization Files

   • System Created Windows Error Reporting

   • Temporary Files

5. Click OK, then Delete Files to confirm

Disk Cleanup also offers the option to clean up system files—helpful for removing old updates and installations.

Method 3: Manually Delete Files from the Temp Folder

Advanced users may prefer this hands-on method:

• Press Windows + R to open the Run dialog

• Type %temp% and hit Enter

• The temporary files folder will open

• Press Ctrl + A to select all files

• Press Shift + Delete to permanently delete them (or right-click > Delete)

• Skip files that are currently in use and cannot be removed

Repeat the same steps for another folder:

• Open Run again

• Type temp (without % symbols) and hit Enter

• Delete the contents just like before

Be careful not to delete anything outside these folders unless you’re sure it’s safe.

Method 4: Use Storage Sense for Automatic Cleanup

Windows 11 includes Storage Sense, an automated cleanup tool:

• Go to Settings > System > Storage

• Click on Storage Sense

• Toggle it On

• Click Run Storage Sense now to trigger immediate cleanup

• You can also adjust settings like:
  • Run frequency (daily, weekly, etc.)

  • Delete files in Recycle Bin after X days

  • Delete files in Downloads after X days

This is perfect if you want your system to clean up without manual steps.

Method 5: Use Command Prompt to Delete Temp Files

For users who like command-line tools:

• Open Command Prompt as Administrator (right-click and choose “Run as administrator”)

• Type the following command:
  

css

CopyEdit

del /q/f/s %TEMP%\*

• Press Enter
  

This command deletes all files inside the TEMP folder quickly. It will skip anything in use.

What Not to Delete

Avoid checking or deleting the following items unless you’re sure:

• Windows ESD Installation Files (used for reset and recovery)

• Download folders, unless you’ve backed up important files

• System restore files, unless space is limited and recovery isn’t needed
  

Deleting critical system files may result in errors or performance issues.

How Often Should You Delete Temporary Files?

It depends on how often you use your PC, but here’s a general guideline:

• Casual users: Every 1–2 months

• Gamers or power users: Once a week or bi-weekly

• After large Windows updates: Always check and remove leftovers
  

Using Storage Sense with weekly cleanup is a great option for ongoing maintenance.
