Upgrade Old Documents to 2007 Versions in MS Word
If you receive a document from a colleague who is not yet running the 2007 Microsoft Office system, the 2007 Office system will automatically open it in Compatibility Mode. However, not all the new features will be available to you. When you close the document, it will be saved in its original format, not in the format of the 2007 release.
If you want to upgrade the file to the 2007 Office system:
1. Click the Office button, and then click Convert.
2. In the Microsoft Office Word dialog box, click OK, and then click Save.
Note: You may want to make a backup copy of the file before you upgrade it . Also, to see when you are working in Compatibility Mode, look at the top of the screen. The phrase Compatibility Mode will appear in brackets to the right of the file name.
