Thanks for the answers. What I really mean is being able to redownload them to a computer. You see, I often have MOBI files on my Mac that I upload via the Send to Kindle app and download to my Kindle and apps. Yay! But then, a month later, I want the mobi file again to -- perhaps -- convert to ePub. Woops, I can't find it on my Mac.
Would be great to redownload it from the personal documents section on Amazon.com.
Get what I mean?
