I can't answer the Sony part of the question
Look at Preferences | Saving ..
There are 2 tabs devoted to to specifying file and folder naming attribute
I chose to have series first because some of the series I read do not have the same Author(s) for every book
I also prefix the title with the series Index (set to 2 chars long) so they appear in proper order in the list the difference shown below
Code:
1 01
10 02
2 10
20 20
