Hi

I have a bunch of wallet.dat files that i want to check the contents of, to see if i've stored a bitcoin wallet that i used for mining back in 2014.

My first question is, if i copied the wallet.dat file to another disk (ssd to hdd) in 2017 would this file be dated as last modified 2014 or 2017?

Second question is about pywallet, is it really safe to use it? i mean it sounds like it could be stealing your keys easily. Like what's the way of using pywallet safely?
