My C: drive is a very small (but fast). I know I can't install Adobe Creative Cloud on anything other than the C: drive, but is it possible to force the temp files to a different drive. I have found a folder on the C: drive labeled "adobeTemp" which is apparently being used to update the various Creative Cloud apps. The updates are failing because of "Insufficient Space" on the drive. I can update one (barely), but if two attempt to update at the same time, I run out of space (and also run into issues with other apps).
I have migrated most read/write elements (including Windows temp files) to my D: drive which has lots of space, but Adobe seems to be insistent on using the C: drive.
