I dont have email address, wallet ID or any other information.
So the wallet isn't yours, you just found it and try your luck by accessing it? This is what I get from your story so I'm sorry if you got offended.
This really looks like to be the case.
If the wallet is his, he could easily click forget password and go on.
He just found some random file that looks connected to the wallet and now he wants to get some money from it.
Anyway, I don't think that file is enough.
Maybe some part of the payload or whatever he has is the wallet id, but he needs the password to use it.
