Yes but now my folders are tidy. Maybe your game development process lends itself to building games while each resource folder teems and seethes with unneeded junk, completely overrun with the flotsam and jetsam of your (and by your I mean my) own past acquisitiveness, but mine does not.
I like having the option to see only the files the project is actually using IN THE PROJECT FOLDERS.
Also, the process of stripping out a whole bunch of files has a heck of a good chance of breaking something in your game (for starters, I gather there are some resources that the deployment utility will not flag as used, even if they are being used, due to the way that some plugins are written) which can be INCREDIBLY STRESSFUL when you are trying to rapidly deploy your game, like if you're up against a deadline, or trying to upload it in time for a comp or jam. Way, way, way, too many times in my life have I been driven to apoplectic levels of stress and panic while trying to navigate what should be the relatively simple technical procedure of removing unused files because I was trying to remove unused files correctly under time pressure and I am never, ever, ever going to have that experience again.
Also also ninja-ninja-bo-binja as you probably figured out I was editing my post while you were making yours so srry don't mean to jump down your throat I clearly just have intense feelings on keeping tidy folders during development.
