URL Protocol View is a simple application, really easy to use, that works to show you all the URL protocols (for example FTPs, telnet, mailto) that you have installed on your PC. They are shown in the principle window of the program.
For each URL protocol it shows you the following information: Protocol name, protocol description, command line that runs when you type or click on the URL, the product name and the company name. Thus the program also lets you enable (F7 key) and disable (F8 key) the URL protocols.
