Go to
Preferences --> Add/Save --> Sending to Device by clicking on the hammer icon in the toolbar.
In the
Save Template input box put something like:
Code:
{author_sort}/{series}/{title}
When you send your files to the device, it will make a folder for the primary author, any series the book may belong to, and then save the book with it's title.
ie:
Code:
Burroughs, Edgar Rice/
Barsoom/
A Princess of Mars.epub
At least it should. There is a list of possible values for the file structure. Modify it to your taste.

\ instead of a forward slash -- I'm on Linux, not Windows.
