Often when we go to delete or move files or folders, Windows will tell you “can not delete the file: the file is being used by another program or user”, but it does not tell us what the program is in the end. Also this happens a lot when you try to reject a USB or removable hard drive as you are told that the device is occupied.
I believe when we have encountered the above problems, the problem persists even we shut down all applications. What we recommend is a free unlocker tool that helps you restore any file/folder’s status so that you can delete/move or modify. IObit Unlocker is free and perfectly supports Windows XP, Windows 7, 8/8.1 and Windows 10 and it is believed to be the best solution for “Cannot Delete” or “Access Denied” problems.
