Was wondering how you change where revit saves it's cache/temp files? Currently it's in C:\Users\Michael\AppData\Local\Autodesk\Revit\Autodesk Revit 2018\CollaborationCache currently and is eating up all my c drive space. Wanted to change to my d drive that has more space to use. Also if thats not possible how do I clean up that folder as it's currently 20gb plus and each project i add to bim360/c4r i'll run out of space quickly.

Using revit versions 2016-2018 if that is needed for reference.

Thanks
