[image] I found that my Appdata > Local > Unreal Engine > Common > Zen > Data folder is 56.1 GB. Anyone know if I can reduce that in anyway? That file size seems excessive.

It’s the DDC. Using Derived Data Cache in Unreal Engine | Unreal Engine 5.4 Documentation | Epic Developer Community UE does do garbage collection on it. You can just delete the Data folder to clear it. It will fill back up again as you load/cook assets in the editor.
