Robert McLaws has always good ideas and the last is really interesting: "ASP.NET 2.0 Web Server Here" Shell Extension.
In summary, it's an addition to the Windows Explorer right-click menu that permits you to setup the built-in web server of the .NET Framework 2.0 on the directory you choose.
It's simply a modification to the Windows Registry, just cut & paste the code above into a .REG file and run it:
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\VS2005 WebServer]
@="ASP.NET 2.0 Web Server Here"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\VS2005 WebServer\command]
@="C:\\Windows\\Microsoft.NET\\Framework\\v2.0.50727\\Webdev.WebServer.exe /port:8080 /path:\"%1\""
A useful little trick...
