As a commandline line junkie, I tend to use Explorer a little differently than those that never leave the Windows GUI. explorer /n will open the current directory in a single Explorer pane with large icons. explorer /e will open the normal dual pane version. explorer /n, e:\is-it-true will open my web directory, e:\is-it-true, in a single pane. The /e parm would do the same in dual pane mode. For automation or shortcuts, this is very valuable. There is another variant that will open explorer in a certain directory and not allow browsing above that directory:

explorer /e, /root, d:\data\officedata

If you browse a certain directory often in Explorer, create a desktop shortcut using these switches.
