Other reasons you can’t perform an action on your file include File Explorer being buggy, your antivirus restricting your access to the file, an installed app interfering with your task, and more.

Close the App That’s Using Your File

Often, you get the above file error when you try to modify a file that’s being used by an app. The app has restricted any modifications to the file, making you unable to make changes to the file.

An easy way to get around this is to close the app using your file. You’ll then be able to make whatever changes you want to your file.

Closing an app on Windows is as easy as selecting X in the app window’s top-right corner. If your app doesn’t quit for some reason, use Task Manager to force quit the app as follows.

1. Right-click your taskbar (the bar at the bottom of your screen) and select Task Manager.
2. Right-click the app that’s using your file and choose End task. This performs an “end process” task, killing the selected process.

 

 

3. Perform your intended task on your file.

 

Restart Windows File Explorer

A minor glitch in File Explorer can prevent you from making changes to your files. In this case, you can restart File Explorer, fixing any items causing you trouble.

You can restart explorer.exe using Task Manager as follows.

1. Launch Task Manager by right-clicking your taskbar and choosing Task Manager.
2. Select More details and open the Processes tab. This tab displays all your CPU processes.
3. Choose Windows Explorer on the list and select Restart in the bottom-right corner.

 

 

 

 

4. Try to make changes to your file.

 

Reboot Your Windows 10/11 PC

If restarting File Explorer didn’t resolve your issue, reboot your entire Windows system. Doing so clears your temporary storage (RAM) and relaunches all your apps and services, fixing many minor problems with the system.

Make sure to save your unsaved work before you reboot your PC, or you risk losing it.

1. Launch the Start menu by pressing the Windows key, then select the Power icon.
2. Choose Restart in the menu.

 

 

 

3. Perform your action on your file when your PC reboots.

 

Clear the Windows File Thumbnail Cache

Windows creates and saves your files’ thumbnails, allowing you to take a quick peek at what’s inside your files. Sometimes, this thumbnail cache goes corrupt, causing various problems on your system.

It’s a good idea to clear this cache and see if that resolves your file error. Windows will re-create this cache and show thumbnails anyway, so you aren’t losing anything.

1. Launch the Start menu, find Disk Cleanup, and open the utility.
2. Select your Windows installation drive and choose OK.
3. Wait for Disk Cleanup to analyze your drive’s contents.
4. Turn on the Thumbnails option in the Files to delete section. This deletes all your thumbs.db files.

 

 

5. Make sure to uncheck other items on the list.
6. Select OK at the bottom.
7. Choose Delete Files in the prompt.

 

Open Folder Windows in a Separate Process

By default, File Explorer launches your folder windows in a single process. It’s a good idea to isolate your folder windows’ processes so that one entity’s issues don’t affect others.

1. Press Windows on your keyboard, find File Explorer Options, and choose the item on the list.
2. Select the View tab on the open window.
3. Turn on the Launch folder windows in a separate process option.

 

4. Select Apply followed by OK at the bottom.
   

 

Turn Off Controlled Folder Access

Your PC’s Windows Security app offers a feature that prevents unfriendly apps from making changes to your files. While your rename, move, and delete actions in File Explorer aren’t unfriendly, it’s worth toggling off this feature to see if that fixes your issue.

1. Perform a Windows search for Windows Security and launch the app.
2. Choose Virus & threat protection on the app window.
3. Select Manage settings in the Virus & threat protection settings section.

 

 

 

4. Scroll down and choose Manage Controlled folder access.
5. Disable the Controlled folder access option.

 

 

 

Clean Boot Your Windows 11/10 Operating System

If your “The action cannot be completed because the file is open” error persists, one or more of your installed apps may be preventing your file actions. If you aren’t sure what app is causing the problem, clean boot your PC, and you should be able to isolate the culprit.

In a clean boot environment, your PC only loads the essential system files and drivers. This isolates all your installed apps, letting you check if your apps are the source of the problem.

1. Access the Start menu, search for msconfig, and select System Configuration on the list.
2. Open the Services tab, select Hide all Microsoft services, choose Disable all, and select Apply.

 

 

3. Access the Startup tab and choose Open Task Manager.
4. Select each Enabled item on the list and choose Disable at the bottom. Then, close Task Manager.

 

 

5. Select OK on the System Configuration window.
6. Restart your PC and try to make changes to your file.

If you can make changes to your file, one or more of your installed apps are the culprit. In this case, uninstall your recently added apps and any other suspicious apps.
