The following MS-DOS command removes ALL attributes (read-only, hidden, system, archive) from ALL files in the current directory:
c:\dos\attrib , (ATTRIB comma)
As a consequence, if issued from the root directory, the following command:
c:\dos\attrib , /s
removes ALL attributes from ALL files in ALL directories on the current drive.


Microsoft has confirmed this to be a problem in MS-DOS versions 5.0, 5.0a, 6.0, 6.2, 6.21, and 6.22. We are researching this problem and will post new information in the Microsoft Knowledge Base as it becomes available.


Both of the following commands remove all file attributes in the current directory:
c:\dos\attrib ,

c:\dos\attrib *.* -r -s -h -a
