yeah, that´s the plan i guess, not worth it with just 0.2
Did you do a permanent delete? If not, it might be in your Windows "Recycle Bin".
Even if it's not, for 0.2 btc, I'd try a freebie undelete utility like
Recuva. May as well, it's easy to try, and it can't hurt....
If you had a restore point in windows might be worth trying it.
FYI restore points in Windows don't typically cover the %appdata% directory.
If I were you I would make a backup of that wallet.dat file right away. In fact, I make three copies on different media. One of them goes in the safe deposit box at the bank. A second one is geo-cashed in an impossible to guess place. The third you could mail to a relative in another state.
Not very convenient with Bitcoin Core, considering you'd need to update all of those backups for every 100 new addresses or outbound transactions you make....
