Don't know if this is what you want, but have a look at this Lifehacker post:

Windows: JDContextMenu is a small
application that adds a variety of
useful shortcuts to the right-click
context menu in Windows.
None of the shortcuts are things you
couldn't do within Windows with a few
extra clicks or with a small 3rd-party
app, but JDContextMenu bundles them
together into a small menu with
one-click ease. You can copy the full
filename to the clipboard, alter the
time and date stamp of a file, run an
MD5 checksum to verify file integrity,
and create new folders—the new folder
tool allows you to create a variable
number of numbered folders in a
series.
JDContextMenu is freeware, Windows
only.
