When you type:

start "C:\Program Files\Microsoft Office\Office\Web Page Templates\Content\Simple Layout.doc"

you would expect the document to open. Due to an error in the Windows NT 4.0 parser, nothing happens.

To workaround this parser problem, type:

start C:\"Program Files"\"Microsoft Office"\Office\"Web Page Templates"\Content\"Simple Layout.doc"

The general syntax is:

start \\"LONG SERVER"\"LONG SHARE"\"LONG DIR"\"LONG FILE"
