This consists of installing and configuring two plugins. Configuring Calibre to strip out encryption from Kindle ebooks

Things are pretty solidly in favor of De-DRM these days, though on the Apple/OSX/iOS platform the use of Fairplay makes decryption very difficult. Over the years there was a back-and-forth of changing encryption and improved de-encryption tools. Therefore, there is a De-DRM plugin for Calibre which makes short work of the DRM. I realize the importance of DRM, but as a consumer it is unacceptable (if avoidable). Removing DRM from Kindle is important so that one has access to what one has purchased. It keeps a metadata file as well as a book cover image (if available) and then one file each for one or more filetypes (e.g., epub, pdf, azw, mobi, etc.). When renaming the author or title, the file folders are renamed as well.

It organizes files in folders based on the author(s) name(s), and subfolders based on the title name. Calibre calls itself an ebook management tool, but really any digital document can be stored in it.
