Try closing any open files or programs using the folder
The most common reason you can’t delete a folder is because a file or program inside the folder is currently open. Before deleting a folder, you need to close any files, programs, or apps that might be using files inside the folder.
Here are some tips for closing open files and programs:
- Close all open window explorer windows, file windows, or other folders inside the folder you want to delete.
- If a Microsoft Office program like Word or Excel is open, close the file. Go to File > Close. This will close the entire program.
- Check the taskbar for any open programs that might be using files in the folder, and close those programs.
- Press Ctrl + Alt + Delete to open the task manager and look for any processes or apps using files in the folder. Select the process and click End task.
Closing open files and programs releases the lock on the folder so it can be deleted. After closing everything, try deleting the folder again. If you still get an error, another program may be locking the folder.
Restart your computer
If closing open files doesn’t work, restarting your computer will force close all programs and clear any locks on the folder.
Here’s how to restart:
- Save any open work in other programs.
- Click the Start button and select Power > Restart.
- The computer will shut down and restart.
- After it powers back up, try deleting the folder again.
Restarting ends any processes that might be locking the folder and gives you a clean slate to delete it.
Use Unlocker to force delete the folder
If restarting your PC doesn’t allow you to delete the folder, you can use a free utility called Unlocker. Unlocker will show you what programs have locks on the folder and let you delete it by force.
Here’s how to use Unlocker:
- Download and install Unlocker from https://unlocker.en.softonic.com.
- Right-click on the folder you want to delete and select Unlocker from the right-click menu.
- Unlocker will scan the folder and show you any lock details. Click the Unlock All button.
- Click Yes to confirm deleting the locked folder. Unlocker will force delete it.
Unlocker is a safe way to remove stubborn folder locks so you can delete the folder. It avoids having to restart the computer when standard methods don’t work.
Check if antivirus software is blocking the delete
Antivirus programs like Windows Defender will sometimes detect a folder delete operation as suspicious and block it. You may get an error that the folder is open in another program when trying to delete.
To allow deleting the folder, you need to temporarily disable your antivirus program:
- Open the Windows Security app.
- Go to Virus & threat protection settings.
- Under Virus & threat protection, toggle Off Real-time protection.
- Try deleting the folder again.
- When done, re-enable Real-time protection.
With antivirus real-time scanning off, you should be able to delete the folder successfully. Remember to turn protection back on after deleting the folder.
Delete the folder from Safe Mode
Starting Windows in Safe Mode loads only the essential drivers and services. This prevents any other programs from locking the folder.
To delete a folder from Safe Mode:
- Access the Windows recovery environment by holding Shift and clicking Restart in the start menu.
- On the recovery screen, select Troubleshoot > Advanced options > Startup Settings.
- Click Restart, and on the startup settings screen press 5 to enable Safe Mode.
- Once in Safe Mode, go to the folder you want to delete and delete it.
- Restart back into normal Windows.
Because Safe Mode has restricted functionality, you can often delete folders that won’t delete in normal mode.
Take Ownership to delete System Files
If the locked folder is in a protected Windows folder like Program Files or Windows, you need to take ownership to delete it:
- Right-click the folder, select Properties, and go to the Security tab.
- Click Advanced, then find the folder owner under Owner and change it to your user account.
- Check the box to Replace owner on subcontainers and objects.
- Click OK until all windows are closed, then try deleting the folder again.
Taking ownership gives you full control to delete protected system folders. Be careful not to delete anything critical to Windows.
