@tgk: thank you for your input on this.
@DarklordShonen: some .pdo files produce a pop-up notepad screen with gibberish on it when you click on them (if that is what you mean); these .pdo files need to be right-clicked on and [saved as...],not opened by clicking on them.I hope that helped you.
Search this thread with the search bar; Dancin' Fool made one and Jf posted it in this thread.I got it as well (thanks JF,thanks Dancin' Fool !)
