I think i'm compiling shaders faster?

Hi everyone, how are you?
Guys i don’t know if this is just in my PC or is this is already known, but i think i found out a way to compile shaders faster. Normally when i purchase a new map, prop or character, i open them already so the engine can load and compile their shaders and i can work on them later, but i found out something curious:

If after i added the new product into my project, if i “move” them inside unreal to another folder, moving them will just take some minutes and when it’s done, all the shaders will be already compiled!

I don’t know if it’s because when Unreal moves the files to another folder it uses more CPU or memory than the regular “compiling shaders” process but i’m seeing a lot of results and working even faster. I just added a 1.2 GB ocean map with fish, post process materials, props and it was fully loaded 5\6 minutes later.
You guys already tried this out?
