Yes, that's where my mentioned keystore file is, I can open it with notepad but what is my privatekey there? All I see is things like:
{"address":"","crypto":{"cipher":"aes-128-ctr","ciphertext":"","cipherparams":{"iv":""},"kdf":"scrypt","kdfparams":{"dklen":32,"n":262144,"p":1,"r":8,"salt":""},"mac":""},"id":"","version":3}

Which long string of numbers and letters might then be my private key?

Edit: never mind, I created a new wallet, transferred all there and turned that into a whale.
