So I been wondering about this for a while. I know if you install UE4 on another computer and sign into your account you can download your bought asset pack into that computer because it’s saved on your account. But the projects your are working on are they saved on your device or in your account like the asset packs?
Projects are saved on your device unless you have set up source control in the cloud(which I recommend).
Dropbox is a pretty quick and easy way to move your project if you don’t already have a better method.
