|.dotx||A Word template with no macros or code|
|.docm||A Word document that could contain macros or code|

The ‘x’ in the above file extensions stands for XML.
If you are sharing documents with people who only have earlier versions of Word, it is recommended to work in compatibility mode to keep the document looking the same as person you are sharing with. If you know that everyone who will see your document is using Word 2010, you can safely convert it to Word 2010 format by clicking the Office Button > Convert. Doing this often reduces file sizes and offers increased functionality.
Hovering over a command that is available only to Word 2010 will display a tool-tip that explains why the command is disabled.
Insert a predefined header or footer
2. Click the header or footer design that you want.
Note If you don't see a gallery of header or footer designs, there might be a problem with the Building Blocks template on your computer. See I don't see galleries of page numbers, headers and footers, cover pages, or equations for information about how to fix this problem.
The header or footer is inserted on every page of the document.
Tip: To change the line spacing, go to the Paragraph section on the Ribbon and click the down arrow on the Line Spacing button . Here you can also change the spacing before and after a paragraph.
