Port Explorer provides real-time port-traffic updates, but you can instruct Port Explorer to pause so that the view is static. Also, the tool saves all activity to a local file that you can view from the GUI. I placed Port Explorer under a heavy load that would typically cause Netstat to slow to a crawl or die, and without hesitation, Port Explorer showed every port as it started up.
Port Explorer's GUI and operations are customizable. You can instruct Port Explorer to show you the filename or the full file path of the program that owns the port. The latter option is beneficial if you're trying to ferret out an evasive program. The main screen contains several columns of information that you can sort with a mouse click at the top of the sort column, and you can drag and drop columns to different areas of the screen without stopping the program. Tabs across the top of the main screen provide several methods for viewing activity. You can customize colors, refresh rates, and even the language. Port Explorer offers eight language choicesit's the only port enumerator to do so besides Netstat. The tool can also display network statistics. . . .
