I had Poser on my C drive, which was running out of space. I realized that Poser was the main cause of the trouble, and I should have to move it. I was not looking forward to uninstalling and reinstalling it, in case I also had to reinstall all the models, clothes and so on that I have collected over the years. I asked in the In Depth Arts forum whether it would be possible to save my runtime folder to the new partition, install Poser, do the upgrade patch, and then replace the new runtime folder with my old one.

Someone said 'yes, but why go to the trouble of uninstalling/reinstalling. Just move all the Poser folders. It works on a Mac'. So I did that, but I also changed the path in the desktop and start>programs links to the new path. It was only a matter of changing the drive letter, because I made sure the path was exactly the same on the new drive. Then I searched for Poser in the registry and wherever I found the old path I updated that. And it works perfectly. There was absolutely no aggravation involved at all - just a simple move of folders and files - which took over 30 minutes.

It freed up 1.25GB of space on my C drive, which is more than enough to keep my other programs happy. It now shares a partition with my hard drive copy of my website. That grows a bit, but not nearly so much as Poser does when I keep adding models. There is 2GB of spare space on that partition, so it should keep Poser happy for the forseeable future.

But if anyone is thinking of moving Poser to another drive - just move it. You don't need to uninstall and reinstall.
