I'm having fun putting all kinds of new content on my Kindle. I'd like to learn if I can edit the titles of files on the Kindle Home page. For instance, I downloaded a PDF of Pride and Prejudice from gutenberg.org and emailed it to my Kindle. On my Kindle Home screen, it shows up as 1362.pdf.pdf. I'd like to re-name it so I'll know what it is, but I'm not finding a way to do that. Any help or advice would be greatly appreciated!
