How to Delete Temporary Files in Windows 11
Let’s face it—Windows 11, sleek as it is, can get bogged down by digital clutter. One of the main culprits? Temporary files.
You know those random leftover files from installs, web browsing, or app usage? Yep, those are temp files—and they can quietly pile up and eat your storage. But don’t worry. Deleting them is easier than you think.
So, if your PC’s feeling sluggish or your storage is mysteriously disappearing, this guide’s for you. Let’s clean house!
What Are Temporary Files?
Temporary files (also called temp files) are just what they sound like—files created to hold information temporarily while a task is being performed. These could include:
- Files left behind after app installs
- Cache files from browsers
- Windows Update leftovers
- Logs and error reporting files
They’re not harmful, but too many of them can start causing issues.
Why Should You Delete Them?
Think of temp files like digital crumbs. One or two don’t matter—but thousands? That’s digital clutter.
Here’s why you should regularly delete them:
- Free up storage space
- Improve system performance
- Keep your PC running smoothly
- Avoid unnecessary errors or crashes
Method 1: Delete Temporary Files Using Windows Settings
Step-by-Step Instructions
This is the most user-friendly way:
- Press Windows + I to open Settings.
- Go to System > Storage.
- Click Temporary files under “Storage Management”.
- Windows will scan and list removable items.
- Check what you want to remove (like Downloads, Windows Update Cleanup, Delivery Optimization Files).
- Click Remove files.
Done!
What Gets Removed?
Depending on your selection, Windows can delete:
- Delivery optimization files
- Thumbnails
- Windows Update cache
- Recycle bin contents
- Temporary app files
Don’t worry—Windows won’t delete anything crucial unless you check it!
Method 2: Use the Run Command Shortcut
Shortcut to Temp Folder
- Press Windows + R.
- Type temp and hit Enter.
- Press Ctrl + A to select all.
- Hit Delete.
You may get some “in use” files—skip them.
Shortcut to %Temp% Folder
- Press Windows + R.
- Type %temp% and press Enter.
- Delete everything in there too.
This folder belongs to your user profile and stores app-specific temp files.
Method 3: Delete Temporary Files Using CMD
CMD Commands to Use
Using Command Prompt can feel like hacking (the cool kind). Here’s how:
- Search CMD, right-click it, and choose Run as administrator.
- Use this command:
- del /q/f/s %TEMP%\*
- Hit Enter.
This will force-delete all temp files in your user folder.
⚠️ Precautions Before Using CMD
- Make sure you run CMD as administrator.
- You might see access-denied messages—ignore them.
- Don’t modify system folders unless you know what you’re doing.
Method 4: Use Disk Cleanup Tool
How to Access Disk Cleanup
- Search for Disk Cleanup in the Start Menu.
- Select your system drive (usually C:).
- Click OK to let it scan.
- Check the boxes next to temp files and others.
- Click Clean up system files for deeper cleaning.
Cleaning Up System Files
Disk Cleanup lets you remove:
- Windows Update logs
- System error memory dump files
- Previous Windows installations (if any)
It’s thorough, but not as intuitive as the Settings app.
Method 5: Storage Sense – The Automatic Way
Enabling Storage Sense
- Open Settings > System > Storage.
- Turn on Storage Sense.
- Click “Configure Storage Sense or run it now.”
Customizing Storage Sense Settings
Set it to:
- Run daily/weekly/monthly
- Delete temp files older than X days
- Auto-clean Recycle Bin & Downloads folder
Set it and forget it!
Method 6: Using a Batch File for One-Click Cleanup
Creating a Batch File
Want to delete temp files with just one click? Try this:
- Open Notepad.
- Paste the following:
- del /s /q %temp%\*
- del /s /q C:\Windows\Temp\*
- Save it as cleantemp.bat.
How to Run It Safely
- Right-click the batch file.
- Choose Run as Administrator.
- Let it work its magic.
Boom—your temp files are toast.
