Hello, when I rename my files I love that I can include the dimensions. eg. 1200 x 800. but I cannot have spaces and need 1200x800...
It makes no sense to go back and manually fix this. can I adjust this element to output with no spaces?
if not a workaround to do it in bulk?
I don't think you can change how LR writes the dimensions, but you can use a renaming utility like ReNamer (for windows) to do it.
It seems that you're doing this when exporting, so you won't have the problem with LR not finding your files afterwards.
