I would sugest you use the calibre "Sending books to devices" to organize your books.
To access it go to:
- preferences » Sending books to devices.
- (If the device is connected) Device » Configure this device
You can personalize how the books are stored in the device (the default organizes by folders from teh author name).
I like to have all the books in the same place so i organize by collection:
Epub/{series}{series_index:| - | - }{title} - {authors}
I then choose on the odyssey to sort by file path
This way i can have all the 1632 books by an order
