After a few crashes, my build of Unreal Engine has taken my entire C: drive. Admittedly I didn’t have much to begin with, but I can’t actually run my more taxing world anymore without a crash due to lack of memory. This will become a problem once I reach rendering. What are my options?
Get something like

so you can see where it’s all going. It could well be your vault, for instance.
