That just removes the photo from the square holder. I'm after the Qimage arrangement where you can choose to display the file names under each other as in explorer
That option to have a list of file names is not available in Ultimate.
Mike has explained before when others have asked for a list, that Ultimate runs differently, and is based on thumbnail + to insert images, and RMB to refine Raws, Creation of higher quality thumbs and cache files for rapid access.
It really serves no purpose during the normal operation of Ultimate.
You still can read the filnames under the empty thumb templates, if you wish.
Sorry,
Fred
