Use a Micro-B Cable to Transfer Data to Your Kindle Fire
It’s easy to purchase or rent content from Amazon, which you can choose to download directly to your Kindle Fire or stream from Amazon Cloud. However, you may want to get content from other places, such as iTunes or your Pictures folder on your computer, and play or view it on your Kindle Fire.
To transfer content to Kindle Fire, you have to use a micro-B cable. This cable has a USB connector on one end that you can plug into your PC or Mac, and a micro-B connector on the other that fits into the slot on your Kindle Fire (which is located next to the Power button).
You can buy a micro-B cable from Amazon for about $10 or search for a cable from other sources, if you like (as long as there’s a USB connector on one end and a micro-B connector on the other, it should work with your Kindle Fire).
When you get the cable, attach the micro-B end to your Kindle Fire and the USB end to your computer.
Your Kindle Fire should then appear as a drive in Windows Explorer or the Mac Finder. You can now click and drag files from your hard drive to the Kindle Fire or use the copy and paste functions to accomplish the same thing.
Using this process, you can transfer apps, photos, docs, music, e-books, and videos from your computer to your Kindle Fire. Then, just tap the relevant library (such as Books for e-books and Music for songs) to read or play the content on your Kindle Fire.
You can also upload content to your Amazon Cloud library on your computer, and that content will then be available on your Kindle Fire from the Cloud.
