Opened Ports Viewer

Certain configurations involve specifying one or more of the computer's open ports, which can be a bit difficult, specifically for inexperienced users. If you wish to figure out these details immediately, Opened Ports Viewer can help you. As the name suggests, the application's purpose is to look up your system's open ports and to display them right in front of you, along with other useful details.

Opened Ports Viewer is delivered completely free of charge, with no ads or hidden fees. The application doesn't need to be installed and it takes up only a small amount of disk space. What's more, the application doesn't create any registry entries, so you can run it from a flash drive.

When launched, the application will immediately display a list with all open ports on your system. Besides port numbers, you can find many other details, like the names of their corresponding processes, remote addresses, protocols and more. Also, the listed ports are color coded, to indicate their status. As a result, ports that are marked for listening, established, close wait and so on can be spotted instantly.

A few filtering options are available on a toolbar. You can select these options if you wish to show nothing but connections or to hide system processes. It is also possible to filter the ports by their protocols. You can decide to show only TCP or UDP ports or both in the same list. Another feature is the possibility of generating reports. The software allows you to export them in HTML, CSS, SSV format or as tab-separated text files.
