Is it okay for me to rename the asset folders and files in my project in my computer's file explorer?

I’ve got lots of asset files and folders I want to rename, but when I try to rename them in the engine, it just makes a copy with that name. So is it okay for me to rename them in my computer’s file explorer?

I’m no expert but I wouldn’t do that. Renaming them in UE4 works just fine but first they are indeed just duplicated. That’s what we call redirectors: Redirectors | Unreal Engine Documentation

Activate the redirector filter in your content browser in UE4 to be able to see them and right click > fix. Once you get rid of them, save your project and all, you should only have the correct .uasset with the correct name left on your disk.

Ok thanks, I’ll try that out tomorrow.

I tried fixing the redirector, but nothing happened. Which one is the redirector? Is it the older file or the newer file?
