I have several wallet.dat files of different currencies from a few years ago.

I'm pretty sure they're empty but I'd like to check it out. Since I only have the wallet.dat (I can't remember the passphrase), I downloaded the bitcoin-qt client and loaded the wallet and let it sync.

When it finished I was able to see the addresses I used and verify that they were 0BTC (well, 0.0000008BTC) with blockchain.info.

Now I want to do the same with doge, ltc and a few more.

Is there any way to list the addresses without having to download the coin client and synchronize it?
