the seed file is always located in another archive, also under a password. I never turn to him - there is no need. It has not been available on PC for many years.
When a software wallet like Electrum generates a new wallet, you're shown the wallet recovery words in an environment whoes safety is basically unknown when it is an online computer. You can make this a rather safe environment when you boot from a knowingly safe system, like TAILS or similar OS boot environments which start from a known state. If you keep this offline during the wallet creation and destroy the environment before it can go online, you're likely pretty safe.
The wallet's recovery words have to be written down offline, no exception here unless you like to gamble. Trying to save the recovery words on a digital device that might go online in some future is a recipe for desaster. Yes, yes, you shout, but it's an encrypted archive. Well, good luck with that. How strong is your encryption passphrase? Are you 100% sure (btw, you likely can't be) there's no malware, keylogger, whatever on your device?
Any online storage of your recovery words weakens the security to that of the encryption password. Typing this encryption password on an online device makes it susceptible to password stealers and keyloggers, not to mention danger from ransomware for digital storage schemes.
When you have written down the recovery words offline or stamped them in metal washers/plates, don't take a picture with your mobile device. Think about it!
Now you probably should try to remember when you handled your recovery words on which environments (online? bad!, offline? better, but doesn't help too much, if the device will go online later) and under which circumstances.
It's way easier to make mistakes than to do it all right. Use a hardware wallet in the future as decent ones are usually not affected by malware on a computer as long as you carefully examine the transactions you're going to sign with a hardware wallet.
