You may get a prompt with the following error below when you attempt to delete a folder in Windows 10 or Windows Server. I ran into this issue when I wanted to delete some residues left from the Windows File System (unmounted Windows 10 image (install.wim) file). Read on to discover how to determine where a file is open in Windows. In this article, we shall discuss how to fix “the action cannot be completed because the folder or file is open in another program: Determine where a file is open in Windows”. Please see how to Hide the Action Center Taskbar Icon In Windows 10, and how to determine the last boot time of a Windows Server.

Reason for the error “The action cannot be completed because the folder or file is open in another program”
There is not a single fix for this issue as shown below. Hence, please follow the steps described below to resolve this issue.
Note: This error is not a permission issue, and as such do not consider checking that.
In order to resolve this issue before employing the hard way to reboot your server which can possibly fix this issue. This is also not recommended because, if the server is a production server, you cannot just reboot it as it is a critical system and must not be interrupted.
Steps to Determine Where a File is Open in Windows
Step 1: Open the program path via Windows 10 Task Manager. This step is relatively straightforward. Open the Task Manager by right-clicking on your Windows Taskbar or use the keyboard shortcut [CTRL+ Shift + Esc] to start the Windows 10 Task Manager.
In the Task Manager click More Details and then, select the Tab “Processes”. As we can see below, there is currently no process using the files.
Step 2: Sing the “Resource Monitor“
To determine where a file is open in Windows, you can use the Resource Monitor which is an inbuilt tool for Windows devices to find which handle or DLL is using it.
Open Resource Monitor, There are a couple of ways of doing this. So, from the Task Manager, Under the Performance Tab, click on the Resource Monitor as shown below.
Alternatively, you can search for the “Resource Monitor or resmon.exe” in the start menu.
Click on the CPU tab. As you can see, there is no associated handler as well. However, if there are associated handles, use the search field in the Associated Handles. With this handle, you can identify the process by looking at the Image or PID column and then kill it.

Step 3: Process Explorer from Sysinternals
This is similar to the method described in Step 2 above. But it depends on the tool you love most.
For more information on the Sysinternals tool and how it can help you determine where a file is open in Windows, see the following article. For more information on SysInternal Tools and how some of the SysInternals tools are used locally on your device. Alternatively, see how to use the SysInternal suit online tool.
Step 4: Reboot the Server
This is usually the last resort but also did not fix my issue.
Unfortunately, none of these steps worked, not even a Server reboot.
Note: MDT was closed, and the “install.wim” unmounted (discarded) and the install.wim file properly cleaned as shown below. See the following guide on how to unmount a Windows Image File (WIM), see the following link.
My solution: I ended up logging on using the local Administrator account and was able to delete the folder! This was not an issue with permission. For issues relating to permission, see the following articles, Folder Access Denied, you require permission from SYSTEM: Unable to delete old Windows folder, Error: 0xc1510111 You do not have permissions to mount and modify this image and You require permission from trustedinstaller: How to delete or rename files protected by Trusted Installer.
