I have been on a quest for the past 2 years to find some old wallets I used back in 2012 and up. I lost interest in the whole BTC stuff in 2015 and now realize my wallet(s) may have quite a bit of BTC sitting idle. Problem is i've replaced hard drives over the years and have overwritten a lot of stuff, etc. I have 26 old drives in a shoebox but there are no typical c:/User/me/AppData/Roaming/Electrum/... type of paths which would make my life easy.
Is there a string I can look for that would tell me when I've found my electrum wallet? I want to see if any of them are still viable/in-one-piece. Or any string that would put me "close" to my wallet where I can sift through the data on the drive to see if I can find it?
Thanks
There's no single answer to that, but for Electrum 1.x wallet formats (2011->2015), searching for the following pattern would be effective:
'seed_version': 4
