Sorry, I wasn't thinking of the filtering. I find it a useful way to collect a list together for my device. For what you are doing, you would still need to manually select the books and add them to a list. But after that you can maintain the list on the device easily.

I have to disagree regarding storing no data on the main memory. In my experiments the internal memory got filled up to 100% (and I have no idea how to clean that up). After a factory reset, on an empty Kobo Glo, I had 1332 of 1361MB available. After copying 220 books on the reader 1266MB remain, which means somewhere are stored, on average, 300K worth of data for each book. And since the books are, on average, larger than 300K it won't be the whole book. When I looked at the mounted volumes, though, there was next to nothing on the internal memory.

This limits the number of books that could be copied even on an arbitrarily large sd card to something around 4.000 books.
Sorry, I wasn't trying to say space wasn't being used. But my understanding of how the devices work and my experience has been that no data is stored on the main memory for books on the SD card, except for entries in the database. This might have changed with FW2.5.0, but I haven't checked. I also don't use the SD card much. There is a card in my Glo, but there are only 10 books on it while I have about 200 on the main memory.

The question is what is taking the space. The only way to know is to connect the device and look at the drive. I am interested to know what it is so that I can look and see if that is happening here and why it is happening. I have just looked at mine, and there is nothing obvious on the main memory that could have come from the SD card.
