Sweeping paper sweeping private keys from 2009-2010 into electrum wallet I have several wallets from 2009 and 2010 that have not been touched since day one.I recieved 25 dollars USD worth of BTC for downloading and running a program in the background. Im guessing i was mining BTC. Didnt think another thought about it. I was alittle irritated because 25 bucks didnt just shoot outof the computer screen!! Lol. 
Luckly my dad never throws away anything. So after scanning 18 hard drives ( it is a whole learning exp.)i have recovered 13 or so private kets and wallet ids. And still looking. 
So obviously i am very slow to do anything and am stuck on this sweeping thing. The files may have had a list of words. I dont recall. They were not encrypted though. So are the priv. keys considered a masterkey? The only options for a standard wallet is seed or master key. One of the files did say rootsomethingor another. None were wallet.dat. i hid one file in a music folder. So where do i go from here? Also,what is xprv yprv and zprv? And what is the purpose of the console for sweeping if any at all? I am not in tye console. 
Anybody have any clue how to guide me on this?
You have to import the keys into electrum. To do that, download electrum on your PC, click on new wallet > import private key > click next and you should see all the coins.
