Ever closed all your open windows only to be hit with “The action can’t be completed because the file is open in another program”? Restarting your PC is frustrating because it closes everything you are working on. What is secretly holding onto your file?
Quick Summary
- Press
Win + R, typeresmon, and hit Enter to launch Resource Monitor.- Go to the [CPU] tab and search for the locked file name in the [Associated Handles] search bar.
- Right-click the locking process in the list and click [End Process].
- Fixes the issue on Windows 10 and Windows 11 using built-in tools without installing third-party apps.
Why Won’t the File Delete Even After Closing the Program?
Even after you close a program window, a background process may still hold an active “handle” on the file.
Think of it like someone putting a library book in their bag and leaving without returning it to the shelf. Even if the application appears closed, Windows maintains an internal handle connection and activates file protection. Even running the del /f force delete command in Command Prompt will fail if another process still holds the handle.
Third-party utilities like Unlocker often come bundled with adware or risk corrupting the registry. Using the built-in management tools in Windows 10 and Windows 11 resolves the issue safely.
3 Quick Ways to Open Resource Monitor
There are three ways to launch Resource Monitor, a native Windows tool that requires no installation.
Choose whichever method works best for you.
| # | Method | Shortcut & Steps |
|---|---|---|
| 1 | Run Dialog | Press Win + R, type resmon, and press Enter |
| 2 | Windows Search | Search for ‘Resource Monitor’ in the taskbar search bar |
| 3 | Task Manager | Press Ctrl + Shift + Esc → ‘Performance’ tab → Click ‘Open Resource Monitor’ |
The fastest way is pressing the Win + R shortcut and entering resmon.
5 Steps to End the Locking Process Using Handle Search
Once Resource Monitor opens, you can identify and terminate the process holding the file.
1. Click the [CPU] tab at the top of Resource Monitor.
2. In the [Associated Handles] section, enter the locked file or folder name into the [Search Handles] bar.
3. Check the search results for the process holding the file (e.g., Word.exe, Excel.exe, explorer.exe, etc.).
4. Right-click the locking process and select [End Process].
5. Return to the unlocked file or folder and press Delete to remove it.
Important Precautions Before Forcing a Process to Close
Before closing processes indiscriminately, confirm that the file is something you created or recognize.
Forcefully terminating critical system processes or files in system folders like Windows or System32 can cause data loss or system instability. Only terminate processes associated with your own documents or familiar user applications.
Files locked by antivirus software or core system services may have the ‘End Process’ option disabled. If the issue is caused by file permissions (icacls) or file paths exceeding 260 characters rather than an active process lock, additional troubleshooting steps will be required.
If you have a file that refuses to delete, press Win + R and type resmon right now.
