I mulled this over last night using the suggestions here, and this is my first attempt to guess an organization:
First Page:
Recent Files
Fiction
Non-Fiction
Library Books
School
Work Files
Manuals
Then under the two main categories, Fiction and non-Fiction:
1. Fiction
2. Genre
3. Author
4. Series
5. <actual book files>
I thought that I'd just put all Library Books in one folder since they expire in a few weeks anyway. As for school, I haven't taken a class for a couple years, but I've been thinking about signing up for a literature class. All my life I've tried to attend at least one class a year, even if it was just a language class or a community school offering. I guess the best way to organize school books is by making a separate folder for each Quarter/Year. I don't know if I have to put the year first to control sorting or if the order I put them stays in that same order. Probably there's no sorting? Here's how I envision it:
1. School
2. 09 Spring
09 Summer
3. <class name if there is more than one>
4. <book titles>
In Work Files I'll just make subfolders as I need them with a separate one for each task.
I couldn't decide whether Manuals belongs under non-Fiction or whether it gets a place on the front page. I decided that if I'm using the PC to organize the folders on an SD card, I can move it later if I want to.
