Define connected file.

Perhaps you want a JFileChooser: How to Use File Choosers (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components)

To get only the "connected files" (whatever that might be) the code could implement a filter as described in the section "Filtering the List of Files"
