I just compiled the Editor from source code. At first look it works fine. The only thing is that the entire root folder ( /UnrealEngine ) size is 63,2 GB after compilation. Can I delete some source code related files for free space? I just want to keep de editor build working.
Dear valued Unreal Engine user,
The source code itself is going to be relatively small compared to the size of third-party libraries and the intermediate directory. By default if you delete those it will likely cause problems when you attempt to compile a project.
What you can do is create an installed build, this is similar to the Windows version of the engine distributed on the Epic Games Store. Potentially that could save 10-20GB. You can find the guide for this here:

Thank you for your continued support,
