I am out of space. Are 3D objects needed?

I can't find any file or folder named 3D Objects related to Elements.  What 3D objects are you talking about?  Are you getting an error message when opening the Elements Editor? 

I'm sure there are many ways to save space on your computer but without seeing it I wouldn't know where to tell you to begin.  If you right-click on your C drive in Explorer and select Properties, you can try using the Microsoft Disk Cleanup utility to delete some unwanted files.  But that usually won't give you much space back.

Are your media files stored on your C drive?  I would suggest moving them to a secondary or external drive.  You can also store your catalog folder on a secondary drive.
