For a better experience with kepubs, instead of renaming the file, use the KoboTouchExtended driver to convert to .kepub.epub when transferring to your ereader leaving the .epubs in your library. This adds in the mass of spans for more accurate highlighting, setting the cover image properly in the metadata, etc.
I ran into one site that used the new Adobe DRM when I had ADE 4.5 installed. When I went back to ADE 2.0.1 and re-downloaded the epub, it downloaded with the old and long broken DRM. I transferred the ebook to my KA1 using ADE 4.5 and was able to read it on the device.
If everything is in it's own folder, that would indicate a newer version of the Kindle app (for PC and Mac). You are likely to see issues if you try to remove DRM from those files. As for the gibberish file names? They seem to match the number displayed for the book when I look in the Kindle store as part of the URL or the mobi-asin number. See this sticky from the Calibre forum for more information Dealing with Kindle for PC/Mac 1.19 and KFX in calibre on issues with the newer Amazon software. |
But why is Adobe's RMSDK incapable of reading EPUB3s? ADE is perfectly capable of doing it so Adobe obviously has support for it too. The books I had trouble with were specifically Japanese releases from the Google Play store. IMO it's still pretty crappy regardless of whose fault it is. Kobo claims Adobe EPUB DRM support and EPUB3 support but you can't do them both at the same time. Misleading I think.
I know about KoboTouchExtended, but if the book is DRM locked I don't think it can touch the file? So without removing the DRM the only thing I could think you could do is rename it.
I also know about the Kindle issue but all I ever use Kindle PC for is Japanese books and to my knowlege no Japanese .kfx books exist yet. Everything still downloads as azw3(Even new releases post 1.19) and I'm too lazy to change.
