<p>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.</p>
<p>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 &quot;reindex&quot; the blocks on the disk.</p>
<p>I am not the most techie person. Thanks.</p>

Shut down the Bitcoin software, and make a backup of your wallet.dat file now. Your coins, if any, will be safe. Then update to the latest release (Bitcoin Core 0.20.1, see https://bitcoincore.org/en/download/), and import the wallet.dat file. 0.8.1 is very old, and I wouldn't bother trying to reindex it left; just synchronize from scratch with new software. As long as you're using unsynchronized software it is expected that your balance shows as 0. Good luck!

Thank you. Should I download bitcoin core v 0.20.1 to my newer (but not brand new PC) where space might be an issue, or just download to the old PC that is running on xxx. Also, I have a "LOG" file in my blocks directory. That I previously backed-up as Log.old, do I need to back it up again before I do this?

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.
