Installing Rhino 6 on your C drive or D drive?

Hello all!

I am just now upgrading to Rhino version 6. My previous version (5) is installed onto my C drive. I have had many many many issues with my C drive running out of disc space, therefor sometimes not allowing me to save my Rhino files, if they are large. My C drive only has about 10gb of free space (no clue how this happened, I only have a couple programs installed on it) and my D drive has hundreds of gb’s of free space. The reason I am curious to if there would still be a benefit to installing the new version to my C drive is because I have an alienware laptop, with large ram, which I believe processes programs fastest through the C drive. Is this even accurate? Or does Rhino not run better on one drive vs another?


I don’t believe there is a difference. Only the drive speed matters

Hi Alyssa - I’d install programs on the same disc as the OS, presumably the fastest of the two, and store all your working files on the other disc. As for cleaning out your C drive, it’s hard to say but by default download folders tend to be there - that folder can get pretty full of pretty large big files, I’d hose it out and maybe point your browser to download to a folder on the second drive. Just a wild guess…

For cleaning out your C, I would recommend SpaceSniffer. The software will tell you what occupys your disk with an interactive diagram

Also keep in mind that as a Windows application, a considerable portion of the tools Rhino needs are Windows tools and must be installed on the save drive as the operating system.
Rhino itself can be installed on any logical drive you have, but not all of it will be installed there.

I’m guessing you need a larger C:\ drive.


One folder that just keeps getting bigger over time is the windows temp folder:


This is the address for my Windows 10 System, I guess it’s the saem with earlier Windows versions. Just replace “Username” with your actual username to find it. You can safely delete all of the content. Some files may not be deletable, that’s OK, just skip them. This can sometimes free up a few GBs.

Also go to “Apps & Features” (also win 10) and see which other programs you might not need any more.
