Compiling UE4.23.1 from source is taking up 90GB+ and growing each time I compile!!

Building the solution should overwrite the original binaries unless if the binaries are currently in use by the Game or Engine. If you modify the Engine module you should just select the Engine Project (UE4) and build that exclusively. You can also build the Game module exclusively. If you don’t want to use the debugger (breakpoints etc) then you could delete the pdb files to save some space but then you won’t know what happened when a crash occur.

100GB is like a minimum working with EU4 though.

Oh, I wasen’t aware that it takes up a min of 100GB. If that’s the case then I’ll live with it.

What concerns me is that I compiled the whole thing once… That gave me a project size of around 40gb I think. Then I modified a single file, hit “build UE4” and next thing my project is twice the size… Are you telling me that is normal? I was under the impression that any files that I change, it will clear and re-compile only the affected binary files. But it seems like it’s creating duplicate file data of the whole project each time or something.
