I'm developing a simple file manager. So, I have two components: JTree & JTable. When I open some folder in JTree, then JTable is updated according to the content of that folder. JTable contains 3 columns: file_type, file_name, file_bytes. The code works correctly.
Now I need to add some more columns to describe each file in JTable, e.g. file_author, file_description, file_link. How could I assign/read these data to/from files? Should I use metadata?
