I recently started using Affinity, and I installed to the D drive as my C drive is small and nearly full.
I tried some image stacking, and started getting low / out of drive messages. When I start digging I found that affinity is using C:\Users\<name>\AppData\Roaming\Affinity\Photo\1.0\autosave for storage and currently using 3G which is all the free space my C drive had. I've tried digging through the registry but so far haven't found settings for that. I also looked through Affinity preferences but don't see anywhere I can fix that. I can't save my work to another drive because it appears to want to write it to the C drive first, giving me a drive full message (though the message sounds like it's the X drive or D drive depending on which I tell it to write to). The C drive is the only drive that is full currently.
How do I change Affinity to use another drive for temporary work? I realize I'm going to lose my current work, because any changes made will require restarting Affinity to take effect, so main concern now is to fix it for future use.
