When books are deleted from the Kindle are the associated index files also removed? As index files take a reasonably large amount of room this would help conserve space. Would a reboot solve this problem?

I was curious about this, too, so a few weeks ago I checked it out on my Kindle 3. When deleting the book, the associated index file was also deleted. I verified this by looking at the index folder before and after the book deletion. No reboot was required.

Note that I only tried this using the file-deletion function on the Kindle itself, since that's the way I delete books after I finish reading them. If one were to delete a book using calibre or your operating system's file manager (Windows Explorer, for instance), then I don't know what the results would be. Probably someone here does, though. If not, I could check it out easily enough, if that's important to you.

That is a good question. Does everything relating to a given book get deleted if you use Windows Explorer or some other means rather than the Kindle's built in delete feature or do associated files remain undeleted from the Kindle?

I can't see how that would be possible. When you use Windows Explorer (or similar), you tell it which specific file you want to delete. Things like annotations and highlights - and indexes - are held in separate files. As the deletion tool would have no way of knowing about those files, it seems likely that they won't get deleted.

Good to know!

The software could easily check for "orphaned" index files. Don't know if it does, but I'd certainly check for that, if I were a Kindle developer.

Not long after I got my DXG, I thought I'd be clever and delete a lot of books via usb. The DXG started using a lot of power - needing a recharge every few days. I think it was "looking" for the books that the index files referred to, not finding them and looking again, looping constantly (just my impression this, I can't prove it). I "cured" it by going in via usb, deleting everything in the "Search Indexes" folder, and leaving it plugged in while it re-indexed everything.

So, in my experience, you shouldn't delete books via usb.

Thanks People - I think you are correct about results when using a USB. I have such a large number of books to clean up that it is my only choice so will remove books and Index files and let the Kindle re-index - easiest way!
