CC doesn't delete ebooks

Or, as usual, What am I doing wrong?

The background to this question is that often upload ebooks I'm designing on to different readers for proof reading and to make sure that the ebook is working as expected.

I've uploaded the one I'm working on now several times to my Nexus 7 2013 running Jellybean after deleting the previous version of the ebook through CC. When I connected the Nexus to my computer running Windows 7 and checked the books folder I found that all the previous versions were still there, taking up space. And there were some versions of other ebooks which I thought I had deleted with CC. They don't show on the book list, but were still taking up space.

What do I have to do to delete the old version of an ebook, and free up the storage space?

Deleting books from CC works for me.

Steps I did:
  1. Send an ebook to CC from calibre.
  2. Verify with a file manager that the book is in the Calibre_Companion folder
  3. Click the book in CC to get to book details
  4. Delete the book in CC's book details
  5. Verify with a file manager that the book is no longer in the Calibre_Companion folder
What are you doing that is different from the above? In particular, where are you finding these other copies? Some reader apps, in particular Aldiko, make copies of books. Some others cache parts of the book.

Thanks, Chaley

I should have mentioned that I'm using Mantano Premium. I don't know if that makes any difference.

I used the same steps as you describe above, but the files I deleted yesterday and today, and the new version I downloaded from calibre are still in the CC folder. I've attached a screenshot of part of the CC folder when attached to my computer with the USB file. The ebook I'm working on is 'No Name.epub' by Wilkie Collins.

Using Windows Explorer over the USB connection is not a reliable way to see files on the device. It can show files that are not there, and also not show files that are there. Better to use one of the free android file managers. I use "File Manager" by Rhythm Software, but there are many others.

Regardless, it could be that you are seeing exactly what is there. When you delete the book in CC, do you see a popup message confirming that the book was deleted? Could you send me a CC debug log? Go to Settings, scroll to the bottom, and choose "Send a debug log to Multipie". Please change the destination address to "cc_logs at charles dot haleys dot org" (no quotes, make the obvious substitutions).

FWIW: one way to correct the list of files given to windows explorer is to reboot your device. To do that, power it off completely then turn it back on. You should see something that indicates that the device is restarting.

Thanks so much Chaley

I tried your last suggestion first since it seemed this simplest. After powering down and starting up again, and connecting via USB cable the unwanted files are no longer there.

I had no idea this could happen, that Windows Explorer does not give an accurate picture of what's in a folder. So I'll now follow your first suggestion and get a proper file manager.

Do you still want the CC debug log? There doesn't seem much need for that now.

Yea, the MTP (cable) interface with Android devices is very touchy and gets confused easily. It is hard to understand how a company as technically competent as Google can produce software that doesn't work in fundamental ways.
