I'm sure that seems excessive to everyone, it does to me. I'm not having problems, per se. I was just shocked. Should I care?
I'm using CC on a semi-regular basis. I've re-located "most" of my user folders to a separate drive from the system disk. I still let "My Documents" live on the system drive. That said, it's size is reported to be much less: 8.7GB vs 73GB.
Should I just move on here or do I have a performance sapping issue that should be addressed?
