Right click on your desk, create a New Folder, name it as you wish.
Throw a 10 words encryption password in a New Notepad.txt,
(you can also use it to secure all your other passwords and account details).
Then put it into this new folder, with your .dat
Right click on your Folder, Click '7-Zip, and 'Add to archive...
Enter your 4 words password, they are the best. And, VERY IMPORTANT,
click 'Encrypt file names' also, or the ante7zip can open you.
And this is it, you made yourself a vault, very safe. You can store this
mini .7z file in a USB key preferably, (offline), even copy several, like me.
Do it in your C: and a USB minimum, for any program can bug.
Simply Right click>7zip>Open archive it.
If you change your notepad, like adding a password,
once you closed it, make sure you said yes to 7-Zip too.
You can also do a safe, with only a notepad, very
convenient for all your internet credentials.
Entrust your passwords to nobody,
not even a software made for it.
Just keep track of your saves well,
and always remember your 4 words.
