I have been installing ALL programs on the C: partition of my SSD and it's now almost full, while D: is not.
I once believed that programs had to be install on C: to work, but I have been told that is not the case. The C: partition, as I understand it now, is reserves for the OS, to make an OS re-install simpler.
So I'm trying to move ALL my programs OFF the C: partition, so the OS will have room to breath. I'm hoping that, in doing so, I will get smoother operation in Lr, Ps and PrE. I'm just hoping, I thought it was worth a try.
I may end up having to re-set my laptop to "out of box" and start over; but I'd like to think that can be avoided.
