I'm not sure that they're actually called wildcards, which is probably why I can't find a list of them anywhere. I'm renaming a bunch of photos, and I've been using the %Y-%m-d_%H-%M-%S setup to get dates in place based on the metadata (when available, thanks Apple).
Is there a list somewhere of all of these variables? They're case sensitive, and I'd like to learn all of them so that as I catalogue thousands of files, I can really make use of the software.
