I download the Unreal engine but says insufficient space. How do I change target
As far as I know it’s still not possible to change the install location 
But install your launcher to a free drive and then the engine will install on that one
You can try to make a junction to fool the launcher into thinking that its installed into another locations. Here is a link to were you can read more about this.

This should work.
Maybe someone could put it on the wiki?
Just create a wiki account and post it 
But… but… you are ten years or such younger and has a better computer 
That’s a good idea, because atm it’s still pretty complicated to post something on the wiki (and you know the solution) 
Oh well I didn’t see KitatusStudios post when I answered. Sure go do it please 
The forum should show that new posts are there when one answers.
