Deleting a read only file using batch file or command

Question

I would like to know a way of deleting a read only file using a batch file or a command.

Suppose I have a DLL file named "abc.dll", and I am trying to delete this file using the following command in a batch file:

del "C:\test\abcd.dll"

It does not allow me to do that and it throws access denied message. However if I change the read only attribute to non read only I am able to successfully delete it.

Answer 1

Specify /F, it will force deletion of read-only files. Also see

del /?

However, that will not work when the file is in use.

Answer 2

del /f will delete readonly files.
