But maybe it would be a very good idea to put another folder in the default? The Fat filesystem is limited to 256 items in the root directory, (and as been mentioned, long filenames take multiple slots). Adding a directory will increase the max to 64000.
The default I showed is the calibre default for all devices. It is specified on the "Sending books to devices" page of the preferences. It is used for the drivers until you configure the actual driver.

The partition is FAT32, not FAT. The number of directory entries in the root directory should be 64K with the added restrictions brought about by long file names. I have definitely had more than 256 sub-directories in the root partition of the device in the past. My current template with the calibre library in it was to move them out of the root while fiddling and serves to separate the books put on just for testing different things from the "real" books. I frequently fiddle directly with the test books while working out what is going on.

As to the arguments about the number of books, I waver between "Why on earth" and "Why not". My Clara HD has nearly 10000 books on it (though a lot are short stories), so I can't really criticise anyone.
