Hot to overwrite a file, that is readonly ??

I must install a new File.
But the existing file is readonly.
How can i overwrite the existing file
or
reset the readonly - Attribut of the existing file ??

The syntax for setting a attribut is SetFileAttributes xx READONLY.
But how can i reset a attribut of a existing file ??

Thanks
Peter

If you use SetFileAttributes filename NORMAL all attributes are reseted

but you have to know the filename. Wildcards are not supported.

Or, if you don't mind a cheesey solution, you can ExecWait an Attrib -r *.blah then you can use wildcards. 😁
