I was wondering about defragging my Kindle. Defragging is a really good thing to do for your computer's drives. Without getting too technical, as you delete things from your computer, you end up with parts of programs that aren't next to each other. Think of it like having a shuffled deck of cards versus one that is all in order (Ace to King diamonds, Ace to King clubs, and so on). It's a lot faster to find the seven of hearts that way. So, I asked Customer Service about defragging, and they sent this:
While it is not advisable to defrag your Kindles, they can be Indexed instead.

PLEASE NOTE: Once the indexes are removed from the device, the Kindle will start
re-indexing all content.

After this point, the device should behave as expected.
