One handy way to work with files in the Windows Command Prompt is to drag and drop them from another window. Thus, if you need to execute a command at the Command Prompt on a file, you can enter the command and then drag the file, which includes the full path, to the end of the command. (Note: Unfortunately, this does not work in Windows Vista, but here's a workaround.)
If you have situations where you need to do a few operations at the Windows Command Prompt involving long path names, especially on servers using UNC path names, the PUSHD and POPD commands are very helpful. Simply execute PUSHD \\full\path\to\use and Windows will immediately map \\full\path\to\use to the next available drive letter starting with Z:\ and working down (e.g., if Y:\ and Z:\ are already mapped, Windows will use X:\). Furthermore, Windows will change to the newly mapped drive immediately. Simply run POPD to "unmap" the temporarily mapped drive.
