Bulk delete news files on Kindle Fire
I'm using Calibre to email daily newspapers to my Kindle fire. This works well, but I'd like to periodically delete old news. I can do this one at a time from the Fire itself, but this is a pain. I'd much rather connect over USB and use the file display on my PC to bulk delete the files. Unfortunately, the file names do not include the name of the news item, so I have no idea which files to delete. Anyone know how to identify the correct files to delete?
