The question is, what are you planning to encrypt with 7zip or similar software? Even though files and folders can be encrypted this way, you should not consider encrypting private keys, seeds, or other valuable data, and storing them digitally for any reason. Use pen and paper, nothing else. Encrypting and protecting some personal documents, pictures, or messages from your kids or missus is one thing, but 7zip shouldn't be used for your financials.
I did use 7zip to encrypt a file document like notepad where I have encrypted it with password and the pc is not connected to Internet at all since we don't have Internet connection at home anymore. Well, I would only do what I stated if the device I used is not connected to the Internet. Mostly, it was eth wallet that time and I still have my wallet secured. I have already stop using private keys or .json file and now I am using a wallet where I need the seed phrase to connect or open my wallet.
