Hi All. Working on a project all day yesterday, and when I opened the work folder this morning, there are 5 AI files in the folder, saved at various times throughout the afternoon. Each has a seven digit file name, no ".ai" tag though. I'm assuming they're temp files that AI has created all by itself, but I had no crashes or system freezes yesterday (haven't had one for what seems like years, to be honest - thanks OS.10!). What's going on? Cheers, Simon.
