One of the most annoying experience when using Windows operating system is unable or cannot delete or remove files and folders that supposed able to delete. When a file is in used or accessed by running program, or a folder that contains file that been accessed, opened, written or used by other user or program, Windows will fail to delete or remove the file or folder with one of the following error messages.

Error Deleting File or Folder

Cannot delete the file. It is being used by another person or program. Close any programs that might be using the file and try again.

File or Folder in Use

File In Use or Folder In Use

The operation can’t be completed because the file/folder is open in another program.

Close the file/folder and try again.

Cannot delete file: Access is denied.

Make sure the disk is not full or write-protected and that the file is not currently in use.

The source or destination file may be in use.

As mentioned in the error dialog box, the root cause of the problem of unable to delete files and folders is because another program, application or user is accessing, opening or using the file, or folder, or file that located inside the folder to be removed. When the file or folder is in used, Windows will lock the file and folder, and block and terminate any other access attempt to the file or folder to prevent any inconsistency of files.

However, in some cases, the problem when encountering such situation is that Windows does not provide a way to trace or check what is the process that is using the file or folder. Sometimes, even if the program suspected to be locking the file or folder have been closed, exited or terminated, Windows still do not unlock release the file or folder for deletion. Beside, there is also possibility that files infected by virus, Trojan, worm and other malware is impossible to delete.
