Answer 1

This information is stored in NTFS. An alternative data stream named "♣ SummaryInformation" is not sure if Java supports reading ADS data through the Colon Notation.

Update: Apparently this should work:

FileInputStream in = new FileInputStream("test.txt:\u2663SummaryInformation"); 

You will need to determine the format yourself.

Answer 2

In Java 7, this may work, but before that, you must use the native DLL to get this information.
