Why is the auto-recover feature so bad?
I have it set to save every 5 minutes and yet it never actually saves anything.
I just had a crash which resulted in a file becoming corrupt:

And there was no auto-recover option when I launched PS, nor are there any files in the auto-recover folder. I lost hours of work.
Why doesn't Photoshop simply keep a duplicate file that autosave every X minutes that you can open in case something like this happens? What is the purpose of the auto-recover thing, how do I actually make it work?
