I installed UE4 on my second HArd Disk (Sata III HDD rather than my SSD).
Even if I did that, some files are still installed on my SSD (C:\Users\xxxxxxx\AppData\Local).
I’m fine with it, but there is a folder called “Derived Data Cache” who takes more than 10Go of my SSD
Since 4.18 you can now set the path for the Derived Data Cache directly through Editor Preference Global Settings.
this was posted by spaceharry in this thread. I am only passing on his information.
Thanks. This worked in 4.26.2 .
Changed it at (by clicking through)
Edit > Editor Preferences > General > Global > Local Derived Data Cache.
This worked and changed the location across all projects.
Afterwards the editor did begin recompiling all the shaders and compressing animations.
