The process of transferring electronic mail messages to a portable universal serial bus (USB) drive involves creating a copy of the email data and storing it on the external storage device. For example, a user might archive important correspondence by saving it from a mail client to a USB stick for safekeeping.
Archiving electronic mail to a USB drive offers several advantages, including enhanced data security through offline storage and the ability to access information on various devices without requiring an internet connection. Historically, this method has been valuable for individuals and organizations seeking to maintain long-term records of communications and ensure data portability.
