Files that cannot be deleted let Task Manager help you get it

In some cases, when you delete a file or folder, you will get a system prompt: "Cannot delete, the file is being used by another person or program." And we have indeed closed this program.
The solution is as follows:
At this time, we press the "Ctrl+Alt+Del" key combination to call up the task manager, switch to the process tab, find the "Explorer.exe" process, and end it. As shown below.

At this point we will find that the desktop disappears, don't worry, click the "File" menu in the Task Manager, run the "New Task" command, and enter "explorer.exe" in the pop-up dialog box. Click "OK" again. The desktop is back, and then delete the file, and found that it can be easily deleted.
