How to delete or rename a file that it's already opened in another program

So how we can modify an already running file?

Generally, Windows won’t let you delete/modify/rename any file that is already running in the task manager. normally you would get the name of this file and look for it in the task manager then end it easily. But what if Windows didn't tell you about where this file is opened exactly or which program has locked this file, a program or a background process may have finished with a file but didn't unlock it properly when it's done. for example, this picture shows what Windows will tell you.

Windows can tell you also this different sentences like ...

• The action can't be completed because the file is open in System.
• The action can't be completed because the file is open in Windows Explorer.
• Cannot delete file: Access is denied.
• There has been a sharing violation.

Here windows tells you where the file or program is opened, but system and windows explorer are system files.

Note: Using task manager to end processes like system.exe or any system files can lead to unwanted system failures or blue screen of death so be careful.
