I have been updating my I/O material as it relates to the Java Programmer Certification exam. I have posted the first item and you can see it at http://www.jchq.net/tutorial/11_01Tut1.htm This Announcement exclusive to Java ranch, check it out and let me know what you think.
I think your notes and questions cover the File class adequately. I also think that a mention listFiles() & listRoots() methods would be helpful? Although I've not faced the actual exam yet, I've come across a question about listRoots() in a mock exam. Thanks
