I have been using Illustrator for a number of years now, and have only been running into this issue recently.
When just using Illustrator, (Opening, saving, closing, etc.) a *lot* of temp files and folders are being generated. Sometimes after using it for an hour or two, I'll have 4-5 temp files, and other times, a 15 minute session will leave me with 30 files + 30 folders.
I have no idea what's causing it, and I can't seem to consistently replicate it.
Does anyone have any ideas? It's starting to become quite frustrating.
