Can't find AutoSave file - is there one?

[DrawnSteelHero]

Normally, I try to save regularly, but sometimes I get lost in my work and forget, so I managed to get quite a bit done since my last save.
Then, when I wasn't paying attention, Windows installed an update and restarted my computer, closing SketchUp in the process.

Now I've opened my model to find a significant amount of work has gone unsaved. I have my Autosave set for every 5 mins, but I'm concerned that because the computer was rebooted, rather than the program crashing, it may have removed that file. But I'm not even sure where the Autosave files are being saved in order to check; there's no entry in the Preferences I can find that can tell me where Autosaves are stored.
Can anybody offer a suggestion that saves me having to redo a couple of hours' modelling?

Usually the autosaved file is stored where the original file is stored.
You can search your disk for the "autosave" word. What I can say though is that sketchup 2014 kind of have a problem loading the autosaved file and it might have lost in the process..
