P: Saving copy not saving over jpg file

you and me both!

Again, disappointed with the latest update of PS 21.1.3, still no fix for this simple issue

Yes this works as a workaround... which take up the same amount of time too as "Save as".. "Quick Export as jpg" or "Quick Export as png"

That's what I have been using, it's just that I wish I didn't have to.

Smh

First thing i see that works. Using "Export" instead of "Save as"

I was saving my files as an eps. It only would save eps files as a copy.

I found a workaround that works. 1st Save your layered file, 2nd Flatten image (from layer panel drop-down menu), 3rd File Save As the file to the file name you want to replace. Once you done these 3 steps your opened file is now the replaced file. No need to find it in your folder to open. TRY A TEST FILE first so you get the hang of it. It works perfectly for me.

When I try to replace a file by saving over it Photoshop creates a copy.

I've dealt with this problem as well, but I found that "Export/Save for Web" actually replace the file and don't add the " copy".  It worked for me perfectly.
