regedit

i need help adding a registry key so i can right click to export a list of folder contents,
i already found that it has to be
[HKEY_CLASSES_ROOT\Folder\shell\foldercontents]
and i know that to open a command prompt in a given directory is
"C:\windows\system32\cmd.exe" /k cd "%1"

and i know that to export the list is
dir /b>filelist.txt

but i am unsure as to how to link the two commands
