I'm trying to move and rename a few part files in an assembly. Usually I right click on the part file and go to the Solidworks subheading where I click on Rename or Move. However, the Rename, Move, and Replace options have disappeared, leaving only the Pack and Go option. Where did those options go?

I've tried to do this on two different computers with the same results. Also, I've tried it with Solidworks open and closed.
