i seem to have lost the .vdi file for my virtual box virtual machine. I am pretty sure i haven't just deleted it. Just to check no one else had i checked the recycle bin and it wasn't there.

i don't have a back up of that part of my system, windows back-up wasn't working on it (i think because the file was too big) so i changed by back-up settings to not include it (dumb idea).

It's just gone missing, any ideas how, or better yet, any ideas where?

If i did accidentally delete it through the virtual box interface would it be in the recycling bin?

When did you lose it? What were you doing for the few days before and after? Installed/uninstalled any software? Any unusual events like power outages or lightning storms? –  Stephen Jennings Dec 15 '10 at 6:00
    
Just before i noticed the problem i deleted a lot of stuff from the download folder. When it said it couldn't find a drive, I thought what i'd deleted was just the .iso of software i'd already installed, so i did a bit of reckless ok clicking. But then the VM wouldn't start. I tried restoring what i thought were the relevant files and that didn't help. Then i restored the virtual-box user settings etc. through windows back-up and tried again, and i noticed the missing file was actually the .vdi for the whole machine. I think it went missing before that though, i don't think that caused it. –  Kirstin Dec 15 '10 at 6:25
    
i can't think of anything unusual i've done between now and the last time the Vm worked properly, all i can think is windows just glitches in very large files? –  Kirstin Dec 15 '10 at 6:26

Use WinDirStat to see where big files are hiding. If you cannot locate it there, I am not sure how to proceed.

will it find files i can't see in windows explorer or viewing folder contents in the command line window? i don't think files can just run away, so it would be where i left it or recycle bin? could this see it if it's there but windows just isn't recognizing it? –  Kirstin Dec 15 '10 at 6:18
    
Hmm I am not sure, you could try it out, it only takes a few seconds, it visually shows you what files take up how much space.. its a great tool for all sorts of things –  madmaze Dec 15 '10 at 6:35
