You hit the problem. It is the file formats, and since I can't get the Kobo itself to show them, I have no idea which one I'd be deleting. Sometimes searching for duplicates using the computer works.

The Kobo shows the format of the books in the library list. It is on the right-hand side with the reading status and size. Older firmware listed it under the title, but that changed well before 3.15. It is also displayed in the book details screen at the bottom in the details tab.

What is Kobo doing when it says it is processing the library or new books?

It is reading the metadata and ToC from the books and adding this to the internal database. The database is used for the library listings and store the reading status, bookmarks and other things it the firmware needs

I had all my books on an ext. SD card and now they are in the internal memory. Every time I've edited the card on the computer, Kobo sticks all the books, new and old, back on the internal memory. Can't Kobo read from an external card and leave the book there?

Sorry, but the firmware does not move books from the SD card to the main memory. I don't really use an SD card, but have kept a card in one of my devices for testing purposes. The books are definitely not moved and I have never heard of anyone else seeing this.

Does it fill up the internal memory first, then use the card?

Yes and no. If you download over WiFi from either the Kobo server or using the browser, it will fill the main memory and then start using the SD card. The same happens if you use the Kobo desktop application, though I have to admit I haven't tested this for a long time.

If you sideload the books, they go were you put them and don't move.

Most of the books were on the external memory card to begin with and now they are not. I download EPUBS since I sometimes read on the Acer at night.


I see no setting that allows that. I also have no more room on the internal memory and it's supposed to hold a couple of thousand books, and I barely have 300.

I'm trying to figure out the easiest way to clean this up and start over.

Will Calibre put all the books in the library on the ext. card? I can clean up the Calibre library, sort the books out, reformat the card on the computer and put the books on the formatted card. Then factory reset the Kobo.

Calibre will put the books were you tell it to. If you send them to the main memory, they go there. If you send them to the SD card they go there.

I'll have to admit, I don't know what is going on. What you seem to be describing, the firmware moving books, just doesn't happen here or have I ever heard of it happening. But, lets confirm what you are saying:

- You put the SD card in your computer and add books.
- You take the SD card out and put it into the Kobo device.
- The device processes the books into the library.
- You connect the device to the computer.
- When you look, the books that you put onto the SD card are no longer there and are on the main memory.

Is that what is happening? Or at least one of the ways it is happening?
