What would be an effient way to moniter if a file is changed? Also a way to moniter if the contents of a directory or it's subdirectories change?

Create a thread that loops every so many seconds (or however long you are interested), and use the lastModified() method in the File class to check if it's changed. Simplest way I can think of.
