I have Windows 10 and a Kobo Libra H20. I have many books, .mobi files, that I can read on my computer with Calibre. When I connect my Kobo to my computer, I can connect and see the File Explorer screen for my Kobo. There are books there I have been able to read on my Kobo. So I copy a book from my computer to the Kobo. The book shows on the Kobo File Explorer Screen. When I double click on the book, it opens and reads in Calibre.

When I eject the Kobo it says "importing content" and then.... the book does not appear in "my books" on the Kobo.

I have tried using Calibre to re-convert the book to .mobi. No joy. I tried converting to epub. Again, no luck.

I read this thread. I saw where it said,
"I assume that you have set the kobo to show all the books (or My Books) not just the I'm Reading" list.

If not, press the Home button. Then press menu and navigate to Books."
When I press "home" I have NO "menu" option on my Kobo Libra H20.

Can someone please help me? Thanks in advance.
