I was looking for an easy way to access my ETC without spending days downloading the old blockchain and making a new wallet and came up with this.. it works and takes about 5mins.

1. Open your Ethereum Wallet and click Accounts -> Backup -> Accounts and locate an account(s) file that you know you had a balance of before the hard-fork.
