Engine(5.5.0) taking up more than 150GB (Linux)

Development Getting Started & Setup
1

Hi all,

I’ve noticed Unreal Engine is filling up my drive pretty quickly.
When I first installed it, it was taking about 65GB. After some days spent working on a project I noticed my system was slowing down a bit (I have the engine on the same drive in which is installed the OS) and it is now about 150GB.

The directories that contains the most data are (these are in the engine directory, not project):

  • Engine/Intermediate ~22GB
  • Engine/Binaries ~70GB
  • Engine/Source/ThirdParty ~29GB
  • Engine/Plugins ~28GB

Also, I read older posts on this topic but they were fairly old and were all about DerivedDataCache that is basically empty on my end.

How can I save some space? Or as a last resort, can I move some of those folders in another drive?

UE: 5.5.0 built from source

I got some errors, don’t remember which ones in particular, just issue sudo make install again and it will resume and compile the rest

Can someone help please?
