Old wallet found – which coin?

Hi there,

I could need some help regarding an old wallet.dat that I‘ve found in my Dropbox. It most likely wont have any coins on it because I always transfered them to shady exchanges – which got hacked sooner or later and never followed the advice „Not your coins – not yout wallet“. Anyway, I want to check the balance of it. Most likely it should be Litecoin, but I also did Bitcoin/Monero and a ton of other shitcoin mining in the past.

Does someone has an idea on how to figure out, whats in there? Maybe without the need to download the full blockchain of multiple coins?

Thanks in advance.
