Where is menu to move DerivedDataCache?

A menu option has been added to move the DerivedDataCache … can anyone tell me where it is located?

Everytime Epic releases a new version of UE4 it stacks up tens of gigs of memory on my SSD. I use to manually move it, but I know a menu has been added to make the change, but I can’t find it.

Any help would be appreciated, and something this important should be reflected in the support documentation, but the section on DerivedDataCache is out of date and does not address the menu option.

Cheers,
John

Yes these is really bizzar situation. Not every one can afford 1GB SSD. Why Epic doesn’t fix the problem is beyond my understanding.
