There are several reasons you might want to save your emails to your hard drive, including recovery after sudden data loss. Backing up your emails to an external hard drive will make sure you always have access to them, even if your account gets attacked by a hacker.
In this article, we will discuss how to back up emails from the top email clients for Windows, Mac, and Linux.
What Is An Email Client?
An email client is a program that enables users to compose, receive, send, access, and manage emails from multiple accounts in one place.
Users typically create folders and labels to organize emails so they can be searched for by details such as time, subjects, senders, and content.
How To Save Your Thunderbird Emails To An External Hard Drive
Thunderbird email is a free application that is simple to set up and easily customizable for Windows, Mac and Linux.
It keeps all your preferences, messages, folders, and other information in a separate file than the Thunderbird program files. This file is called your profile directory. You need to use it to back up your emails.

Save To Hard Drive
Highlight all the folders, files, or zip file you created and copy the files. Navigate to the external hard drive where you want to save your emails and paste them in.
