Hello,
thank you for the information.
The usage of OSProcess would be fine. E.g. if I could execute
OSProcess command: 'del /a:R test' to delete the read-only file named
test. But unfortunately I get an error when I try to do this.
OSProcess command: 'rm test' on the other hand does work. But I
cannot delete read-only files with the rm command (at least I don't
know how).
So if there would be a way to use the del command with OSProcess I
would be happy...
Robert
