I'm absolutely new to this, but I decided to try myself in game development with Unreal Engine. It's complicated by the fact that I have Linux and had to compile everything from the source code myself. So, at the moment I have two problems that I have no idea about.
1) The folder with my Unreal Engine weighs as much as 75 gigabytes. Is that okay? If not, then how can I reduce it? (since I didn't have enough space on my laptop to install, I had to do a perversion - compile the source code that was on my external hard drive, and the program additionally tightened all the dependencies)
2) When I run the IDE, the entire interface is on the wrong scale (in the screenshot). How can I fix it?
Again, I'm totally new at all this, and I don't even know which way to dig to get the information I need.
This isn't a very good answer since I have yet to try out the steps myself. It's meant to provide a direction toward an answer, but it's too long for a comment. Please edit this answer or answer separately if you have confirmed it or have a better one.
From the documentation ( https://docs.unrealengine.com/en-US/Platforms/Linux/BeginnerLinuxDeveloper/SettingUpAnUnrealWorkflow/index.html ), note that you can reduce the size of the downloaded source by downloading the ZIP instead of cloning the repo.
In addition, once you have compiled the binary and ensured that it's working, I think you can safely delete all the files outside the Engine/Binaries directory.
With respect to scaling, you should be able to scale the UI down by Window > Developer Tools > Widget Reflector. (from https://forums.unrealengine.com/unreal-engine/feedback-for-epic/9533-high-resolution-display-support-for-editor)
