I have two drives, one for my os and programs that take a lot of speed and one for my mass storage
so I have these projects from my old computer and I moved them to my unreal projects folder and when I open up the launcher all it did was ask me if I want to associate some project files with the launcher and all it did was move it to my c: drive which I don’t have enough room on. So I uninstalled the launcher and installed it on my mass storage drive and it did the same thing, is the launcher like tied to the c: drive
im pretty sure if you make a new project and choose a different drive, it will use that as the default location from now on
When you are creating a new project, on the second screen where you choose feature packs there is an option at the bottom that let’s you change the folder where the project is stored and the project name.
You can also just move a project to another folder and just use the “browse” button when launching UE4 to navigate to the new location.
