Ah, it sounds like "Main Memory" in this case is actually the SD card. Main memory is accessible by apps but not as a drive, as you noted. Thus it's a bit confusing the way it's presented but it sounds workable.

The issue then would be the ability to read two different locations:

1. Where the books end up.

2. Where the books need to be placed to be "imported" by various readers.

In my case books end up in /ebooks with a typical directory structure of Author/Book/Book.epub but they need to be copied to /ebooks/import in order to get there. Just placing them in the former won't allow aldiko to work with them.

And, to let you know, it IS working like that. My issue was trying to send to the SD card as far as Calibre was presenting it. So again, it'd be great if this was explained somewhere and also if there was a setting to where to look for what books are actually on the device in question if they're in a different location from where you drop them off.
