Document properties store information about your document. This information includes title, author, and statistics about the document. You can also use document properties to store keywords and comments.
Document properties come in handy when you need to know more about a particular document. You can also search document properties; this makes it easy to find the exact document you need.
Some information in the document properties dialog box is completed automatically. However, it is easy to forget to complete the remaining information. In that case, you can have Word prompt you to complete document properties.
Click the Tools menu
Select Options
Open the Save tab
Select Prompt for document properties
Click OK
When you close a document, Word will prompt you to complete the document properties.
