The thing is, 38 chars is arbitrary limit from bygone era when screen space was precious and UI had to make sure dialog boxes fit no matter what. It's not like Apple can do hidpi UI but can't overcome 38 character limit for file name entry widget. It'd be small qol fix but no, for some reason other commenters need to defend it and point out that OP should just organize their files better. I don't understand, truly I don't.
