@hexafraction: Thanks for explaining what JSON is. I opened it up and it doesn't look like what you describe for JSON, so I guess its possible, a good chance that its not electrum...hmmm.
@hcp: There are indeed a bunch of random characters and it looks like alien code or something. Possibly litecoin core wallet? dont know... will look into it further on litecoin forums. but can't say that I remember downloading the entire network in the past... but maybe i did .. who knows.
I just know one thing and that is its a real issue that i cant open this file, when i never encrypted this wallet and saved it on to a local external drive. Electrum should have warned us a little more visibly on their website that this could've been an issue in the future.
a big part of it is my fault for not saving the private keys, which was a class-a stupid thing to do, but i did test it after saving and opened it right up, so i figured, it would be fine in the future. I wouldn't have ever imagined this being an issue.
oh well... live and learn
It is not an electrum wallet so stop dissing electrum. Electrum wallets were human readable json like code. It didn't offer full wallet encryption back in 2013 so that does not apply to your situation.
