lol I'm trying to avoid having to download the full btc core node as it is 350gb, I'm sure there are other ways I can gain access to my private keys and address and transfer/import that wallet
As far as I know, downloading 350 GB should be okay on most home internet connections nowadays. But if you really don't want to: install Bitcoin Core, load your wallet, and check the receiving addresses in
a block explorer.
If it shows anything, you may be rich
If you don't want a block explorer to know your addresses,
download a list of all funded addresses and check it locally.
