Kindle 2 User’s Guide 2nd Edition 82
The illustration below shows a Kindle and a laptop computer connected through the USB cable.
When you are connected to your PC, your Kindle will go into USB drive mode and its battery
will be recharged by the computer. Your Whispernet service is temporarily shut off and you will
not receive any of your subscriptions while in this mode. Also, your Kindle is not usable as a
reading device while you are in USB drive mode, but will return right to where you were when
you unmount the device from your computer.
Tip: If you'd like to continue reading your Kindle while its battery is being charged by the
computer, you will need to release it from USB drive mode by unmounting or ejecting the
Kindle from the computer. Note that it is always best to use your computer to unmount or eject
your Kindle before disconnecting the USB cable. Consult your computer manual for details on
how to properly disconnect a USB storage device.

8.2 Handling Files through USB

Managing Your Documents
When your Kindle is connected to a computer and mounted as a USB drive, you will see three
default directories or folders. The one called "documents" contains all of your digital reading
materials like books, newspapers, your My Clippings file, etc. The "Audible" directory is for
your audiobooks, and "music" is for your MP3 files. You can add Kindle-compatible files to
these directories, and you can copy, move, or delete the files that are already there. The computer
file formats that you can read or listen to on your Kindle are listed below:
• Kindle (.AZW, .AZW1)
• Text (.TXT)
• Unprotected Mobipocket (.MOBI, .PRC)
• Audible (.AA, .AAX)
• MP3 (.MP3)
