In August of 2012 I bought & spent a few BTC.  The next month I forgot about my bitcoins when I reformatted my computer.  Since then I've assumed that they were lost forever, but I was just looking through an old backup of my computer and found this (OS is Windows Vista) - http://screencast.com/t/q9TZxLfs9V7

Would my BTC be somewhere in those files?  If yes, how would I go about "getting them out" so I can use them again?
