Tried to create management through explorer -everything "corrupted"?

Hi! I was told I could have my classes in categories by creating folders and drag&dropping them in those folders. Well, I did just that, reloaded the project, and was left with VS detecting only the ones in “utilities” folder. Well, I put them back where they were, and now none of them show up. This is getting a bit irritating, and I am about to recreate project and copy-paste the code from old classes to new ones, unless someone could tell me how to fix this mess?

UE4 has rules about what can go where in order to support it’s module system. You can read the details here: Gameplay Modules | Unreal Engine Documentation Looking at the UE4 source code is also instructive if you want to organize your code. Look at the Core and Engine modules.
