user56182: A few years ago I mined a couple of alt-coins. Now I have approximately 5 wallets which are named in non-suggestive way: wallet_01.dat, wallet_02.dat, ..., wallet_05.dat. Each of them has reasonable amount of coins, also I have no idea how much exactly and what coin correspond to each wallet. Now I would like to restore some order by checking what do I have and how much.
Is there a way for me to figure this out? I do not remember exactly what these alt-coins are but have approximate ideas (probably can try to remember and select 30 potential candidates).
With this, I clearly can try each of the alt-coin client, wait for sync (may be do not even need this) and try to open each of the wallet. This will be very slow and because I am not 100% sure I will be lucky with my 30 crypto-coin guesses might take even longer.

So, is there a way to find a corresponding alt-coin for a wallet. Even maybe finding how much coins are in the wallet without downloading the client?

user2306: I think you can narrow your search space. If you're on linux, and you run the command 
strings wallet.dat | grep purpose | less

you should get a list of all of the addresses in the wallet, even if the wallet is encrypted. You can check that against a list of address prefixes for each altcoin.
If you run
strings wallet.dat | grep tx | less

you should get a line for every transaction that wallet has sent or received. (This only catches transactions that were present the last time the wallet was open. If someone sent you a billion cryptobucks ten minutes after you logged out, this will not catch that.)

user56217: Just open each file and look for name"
the address will be after that.
