Using URLProtocolView

URLProtocolView doesn't require any installation process or additional DLLs. Just copy the executable file (URLProtocolView.exe) to any folder you like, and run it.

Warning: don't disable the mailto protocol

Windows operating system has a strange bug with mailto: protocol.
When the mailto protocol is disabled (which means that there is no default email program for handling 'mailto:' URLs), and you click or type a mailto: URL, Windows displays an error message saying that there is no default email program, and then, unexpectedly, dozens of Internet Explorer windows (35 - 55) are opened quite rapidly, until there are no system resources to open more windows...
Due to this bug, it's recommended to avoid disabling the mailto protocol.

However, if you want to watch this bug, just for fun, here's the steps to reproduce it:

  1. Run URLProtocolView, select the 'mailto' protocol entry, and press F8 to disable it.
  2. Go to the 'Run' dialog-box of Windows or to the address bar of Internet explorer and type something that begins with mailto: , for example - mailto:nirsoft@nirsoft.net (You can type any email you like)
    press enter to activate the URL, and wait 5 - 20 seconds.
  3. Windows will display an error message. click the 'OK' button
  4. Watch the opening windows show :-)

This bug is reproducible on Windows 98 SE, Windows XP/SP2, Windows Vista, and possibly on other versions of Windows.

Command-Line Options

/stext <Filename> Save the list of all URL Protocol entries into a regular text file.
/stab <Filename> Save the list of all URL Protocol entries into a tab-delimited text file.

/sxml <Filename> Save the list of all URL Protocol entries to XML file.
/sort <column> This command-line option can be used with other save options for sorting by the desired column. If you don't specify this option, the list is sorted according to the last sort that you made from the user interface. The <column> parameter can specify the column index (0 for the first column, 1 for the second column, and so on) or the name of the column, like "Description" and "URL Name". You can specify the '~' prefix character (e.g: "~URL Name") if you want to sort in descending order. You can put multiple /sort in the command-line if you want to sort by multiple columns.

Examples:
URLProtocolView.exe /shtml "f:\temp\u.html" /sort 2 /sort ~1
URLProtocolView.exe /shtml "f:\temp\u.html" /sort "Type" /sort "URL Name"

/nosort When you specify this command-line option, the list will be saved without any sorting.
/wow64 Only for x64 systems. By default, URLProtocolView displays the URL Protocol information for x64 applications. If you specify this parameter, URLProtocolView displays the URL Protocol for 32-bit applications running under WOW64.
