What Causes the Error 0x80070091?
This error usually occurs because:
- The folder is corrupted or partially deleted
- A background process is locking it
- You don’t have proper permissions
- The file system has inconsistencies
The folder may appear empty, but something in the background is keeping it from being deleted.
✅ Methods to Fix the Issue
Here are a few proven methods to delete those stubborn folders.
1. Use Command Prompt (Admin)
One of the quickest solutions is to use the Command Line:
Steps:
- Press
Win + Xand select Command Prompt (Admin) or Windows Terminal (Admin) - Type the following command:
rmdir /s /q "C:\Path\To\Folder"
/sremoves all subfolders and files/qruns the operation quietly without confirmation prompts
Replace C:\Path\To\Folder with the actual path to the folder you’re trying to delete.
2. Take Ownership of the Folder
If you’re getting access denied errors, ownership might be the issue.
Steps:
- Right-click the folder > Properties
- Go to Security > Advanced
- Click Change next to the Owner field
- Enter your username and press OK
- Check Replace owner on subcontainers and objects
- Apply and exit, then try deleting the folder
3. Boot into Safe Mode
If a system process is locking the folder, Safe Mode can help.
Steps:
- Press and hold
Shift, click onrestart, and don’t release ‘Shift’ until you see “Choose an option” - Press Troubleshoot
- Press Advanced options
- Press Startup Settings > Restart
- Pick Safe boot from the list
Alternative Steps:
- Press
Win + R, typemsconfig, and press Enter - Go to the Boot tab and check Safe boot > Minimal
- Restart your PC
- Try deleting the folder again
After you’re done, go back to msconfig and uncheck Safe boot to return to normal mode.
4. Use PowerShell
PowerShell provides more control than CMD in some scenarios:
Remove-Item -Path "C:\Path\To\Folder" -Recurse -Force
5. Run CHKDSK
Corrupted file systems can prevent deletion. Use CHKDSK to fix errors.
Steps:
- Open Command Prompt as Admin
- Type:
chkdsk /f /r X:
Replace X: with the correct drive letter.

If none of the above works:
- Try renaming the folder and rebooting
- Scan your system for malware
