If you have Full Control of a folder, you should be able to delete any file in it, even if the file is set to No Access or Delete (only).
Windows NT Explorer has a bug that prevents this, caused when it attempts to move the file to the Recycle Bin.
To work around the problem, perform any of the following actions:
- Add Read permission to the file.
- Use File Manager (WINFILE.EXE).
- Use the DEL command.
- Hold down the shift key to prevent the file from being moved to the Recycle Bin.
