,
I have two versions of ue4 4.6 installed, one source from github and a normal downloaded one which I updated through launcher.
I’d like to uninstall github one since it’s taking up 23gb on my drive.
when I got into my control panel I can only see one program called ‘unreal engine’, but I don’t want to uninstall them both.
how do I delete github version without affecting my other copy of ue4?
thank you!
Hey HSbF6,
If know where you put GitHub version, it’s as simple as deleting folder. There’s no uninstall process necessary for GitHub builds. Hope that helps!
oh sweet, thank you! 
Why sources so weighty?
Hi 2rusbekov,
When you get engine from GitHub, you’re getting full, uncompiled source for engine. binary version already has a lot of this built, so it’s much smaller, but if you want to edit source you need to get everything and build it yourself. It ends up being a much larger folder.
I cannot delete UnrealEngine\Engine\Saved\Config\Windows. I am admin and cannot change rights on folder to delete it. No solution from Google yielded any results. Is there some way to delete that folder or get access to it?
I am able to recover all Engine files if that is of any help.
Edit: Nevermind, I solved it by booting Ubuntu from DVD and deleting everything from there.
