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. Check balance here http://classic.aakilfernandes.com/#
2. Go to myetherwallet.com, click "send ether", and click open wallet file. Open and unlock the same wallet file you found in step 1.
3. You will see you ETH balance and ETC balance on the left side. Click ETC Only transfer, and transfer everything to Poloniex or wherever you want.
4. Buy beer with your free money.
P.S. I moved all my ETH to another address as well..
