Thanks NiLuJe and kcn1 for your help. I really appreciate it.
NiLuJe, well you made me giggle, always a good way to start the day.
Anyway, I did watch your video cocking my head a little. Thanks for that. When I type in ":dm" I am not seeing any files on my kindle with similar names, either on the kindle or in my documents folder that I access through usb. But I'll try once more. I do sometimes ditz out but I think that I would notice files with those long names, I hope.
But I have a better idea of what files to look for, thanks to your video.
kcn1, I will try your suggestion later. Although, I have deleted some extraneous files in my documents folder while on my mac and restarted. I think they are gone, but I'll do your suggestion again later. I'll delete one of the NY Times that I have already read.
Also, yes, I know about removing the recommended books that clutter the bottom third of the screen. And thanks for the confirmation that the kindle will phone home after I have a read a book to get more recommendations for me, which will be there the next time I sync.
