Set the file extension to Uppercase when I export to edit in Photoshop.

Question

Hello Adobe TeamWhen I need to refine the edit in Photoshop I export directly from Lr to Ps. But when it’s time to save the file and return to Lightroom I always get a filename with a Lowercase extension. There is no option to set it to Uppercase [image 1], unlike the export dialog [image 2].  I tried to rename the file manually within Lightroom, rewriting the extension to Uppercase in the Filename field, but doesn’t work. It reverts to Lowercase on pressing enter to confirm the change.I also tried renaming outside Lightroom, in the Finder, then right click on the image in Lr. But there is either no option to synchronize only the file. Synchronizing the folder is not always desirable. there might be images I don’t want/need in Lr. I’ve also noticed that renaming outside Lightroom, when I get back into Lr, there is no alert badge on the file preview signalling the external change.By the way, what I’m asking here is Uppercase extension when exporting from Lr to edit in Ps or External Editor.Thank you for your attention.Best RegardsMarco Lanciani

Just as a point of reference: LrC is a cross-platform application for MacOS and Windows. I know that both do retain and present a case-specific name, but may disregard the difference in some ways (as might the Catalog itself). As a concrete example, if I try to save a brand new file or make a new folder whose name differs only in letter case from something already there, Windows (for example) disregards differences of case in refusing to do that:

Mismatches of case importance / unimportance between what the Catalog does and what the OS does are notorious. So case sensitivity is a tricky issue in practice. While I can think of a couple of workarounds to achieve this, those would be slightly-to-a-lot more laborious.

What is the practical driver requiring an upper-case file extension, in your usage, out of sheer curiosity? I only ask because the opposite requirement seems to be widely encountered.

Giving the user that choice of case does seem like a good idea - with no downside I can see.
