Can you advise me on upgrading my wallet and bitcoin software. Are there files I should save before upgrading? what should I upgrade to? Other basic questions.
I have a number of bitcoin files in my block folder *.dat in a file folder created in 2008 (when I gave bitcoin mining a very short try, but freaked out with my PC nearly grinding to a halt). Not sure if this means I have any bitcoins. I have a wallet, that is showing zero bitcoins but isn't synchronised. The PC is running on windows 7. That last time I looked at my PC was in 2018, but I wasn't able to synchronise the files fully, but thought I would try again. My OLD PC is currently trying to "reindex" the blocks on the disk.
I am not the most techie person. Thanks.
