Are there btc in this multibit wallet I have several multibit wallets I put in storage years ago, and I'd like to check if there's btc in them . I see wallet IDs for 'receive address'  in the .info files - if those show 0btc does this mean the wallet is empty? Or is the receive addr not where btc would be stored?
I'd like to verify there's actually something in there before banging my head against how to retrieve from what looks like an unsupported wallet type.
The dirs look like:
wallet1.info
wallet1.wallet
wallet1-data
    key-backup
    wallet-backup
    rolling-backup
    wallet-unenc-backup

and the .info files look like (for wallet1 in this case):
multiBit.info,1
walletVersion,3
receive,1GFM...RGdp,
property,walletDescription,wallet1
property,walletBackupFile,C%3A%5CUsers%5Cjeremy%5CDocuments%5C%5Cwallet1-data%5Crolling-backup%5Cwallet1-20131201123906.wallet
property,receiveAddress,1GFM...RGdp
property,receiveLabel,
First dump your keys using the instructions here
Then open a new Electrum wallet, ask it to &quot;Import private keys&quot;, and paste your private keys there.
Then you will be able to spend from there if you have coins.
