A while back I mentioned that you can just enter sendto in the start/run field and it would open your sendto folder.  There are many of these shell folders – special folders that may be on disk, or may be fabricated by the OS.  The “correct” way to reference these is with the “shell:” prefix.  So you can specify shell:sendto, shell:startup, shell:favorites, etc. [more]

The full list is in your registry at

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions

Note: The name in the registry does not always match the name you see in explorer.
