Earlier, emailing document from your Pc to
personalized kindle email address was the prime option for transferring files from your Pc to your Kindle device or you could use a USB cable to connect both the devices & transfer files.
You're going to have to enter your Kindle email id and your
authorized kindle email address (don't worry, I'm going to show you how to find both in the video).
The ones I don't use or have duplicates of have been great gifts for family / friends with a Kindle (I just email it to
their kindle email address).
You could get files onto your Kindle by e-mailing it to
kindle email address or connecting it to your PC through a USB.
Your kindle email address will be shown in the second column.
Now head to your email account, attach the document as one of the file types listed below, and send it to
your kindle email address.
