I just downloaded Illustrator CC and it crashed while I was working on it.
1) How/where do I recover the file
2) Where do I set the autosave options?
Illustrator will, on very rare occassions, recover a file after a crash. it's EXCEPTIONALLY rare though. It has something to do with how and why the crash occured and only in special instances is recover possible. If Illustrator does not recover the file when you relaunch the app, there's no other way to recover anything.
No one here will know why specifically. Adobe doesn't share development information. One possible holdback may have been the fact that Illustrator was a 32bit app up until CS6. Now that it's a 64bit app, the prospects of an auto-save or recovery feature are more likely from my understanding.
As pointed out by Scott, you will never get an official reason.
However, I don't think 32 bit vs. 64 bit does explain it. InDesign, for example, had got recovery mechanisms about 12 years ago. At that time it was certainly not a 64 bit programme …
Out of curiosity, does anybody know why?
I believe I remember someone once saying that a long unexpected saving would be quite disturbing, and potentially wrecking, so it was better to control it oneself.
Obviously, this requires that lack of total immersion.
But as it has already been said: no one knows; or no one that knows has ever told anyone here.
There is pretty solid AutoSaver for Windows — http://www.door2windows.com/autosaver-save-the-file-you-are-working-on -automatically/
