Setting File/Open to Use A Certain App to Open a File Type

[PaulG]

I would like to get Photoshop to open my .TIF files.
Another app is now set to handle these. But when I go
into Control Panel>Folder Options>File Types and make the
change, Photoshop opens OK (as the chosen application),
but the chosen .TIF file fails to load within it.

Can someone tell me how to handle this?

You need to follow up the change to Photoshop with a ''%1'' variable. (Sometimes with quote marks; sometimes without; I'd bet on without, but would have to try it to be sure). E.g. [Path]\Photoshop.exe (is that the name of that app?) %1.

There's a set of rules about when to use quote marks and when not (use if there are spaces among other rules) and there are apparently exceptions to the rules. Try it both ways, and you'll find which one works.
