If you have a lot of Word documents and are not sure which one contains the information you need, Microsoft Word 2007 allows you to preview a document within Word without having to open each document.

Open Word and click on the Microsoft Office Button and choose Open.

The Open Dialog box will appear.  On the right hand side of the toolbar click the down arrow on views and choose Preview.

This will open the preview pane.  Click on any file on the left hand side and preview what inside the file.  When you find the file you need just click Open.
