Transfering Raw game correctly

Ok so I plan on whipping my computer for personal reasons how ever I want to put all of raw game onto a HDD and put it back on computer when I am done. I have attempted this before how ever the references where wrong and completely messed the game up and threw my blueprints off. So I geuse im asking "how do I transfer a Raw game with its references being correct?

are you talking about copying the project over or a built game?

Its a project

Then just copy the entire project folder? All of the assets should exist inside of the content folder of it. For external files you will just want them to be in the same location as on your previous PC or you can change around their asset link for Media Files etc

Is there away to move the external files into the program file without affecting the project?
