You cannot delete a file when it is in use in Windows. When a process opens a file, it locks the file while it is in use. You will get the error message that you cannot delete the file because it is in use by another process. All operations to the file like delete, rename, open, edit, etc. will be disabled while the file is locked by another process.

This is how you can quickly copy the file without a lot of hassle. Replace and with the source and destination paths. Some file extensions are blocked by VSS like .OST and PST Outlook data files. To copy these files from VSS, you should delete the file extensions from the registry first. Go to the following registry key and delete your desired extension:

Close the program

If you are using the latest version of Windows 10, please note that it gives more details than the generic error we mentioned above. Most of the time, Windows can identify the program that is locking up the file, and will specify this in the error message. For example, in the screenshot below, Windows identifies and specifies that the PDF file is open in Foxit Reader. When I close Foxit Reader, I’ll be able to delete the file without any warnings. But some processes become stubborn and don’t unlock the file even when they are closed and the file won’t delete whatever you do. For this, we will show you how to force delete a file even if it is locked. You can also force delete a folder using similar techniques. Let’s discuss some of the instant solutions if Windows is not showing the process name which is locking the file.

Restart Windows Explorer

If a file is opened by Windows Explorer, it will get locked until Windows File Explorer releases it or we restart the process. To restart the Explorer process in Windows 10, follow the steps below: If you are using Windows 8.1, Windows 7 or earlier, you should follow the steps below: This will start Windows Explorer again. After restarting, try deleting, moving or renaming the file. If you still get access denied, move on to the next solution. If these steps resolve your issue and you get this issue frequently, you should launch file explorer processes in separate windows. This will make sure that you don’t lose your work just because one file is stuck and you have to restart the Windows Explorer process. To launch each file explorer process is a separate window, follow the steps below: This makes sure that only the problematic Windows Explorer process gets closed or restarted.

End process using the Task Manager

If you know that it is not Windows Explorer and another specific process is locking the file, you can simply go to Task Manager, select the process and press the delete button. This will kill the problematic process. If still files access is denied, try the next solution.

Restart the computer

When nothing works, restarting the computer can be beneficial. If you don’t get this problem frequently, try restarting your computer. A clean boot is preferable because it will not cache anything in the memory. If you still can’t delete a file, probably a system process is locking up the file and you will need third-party file unlocker tools discussed below.
