To save a version, do one of the following:
- Choose File → Versions and click Save Now. Enter comments that describe the version.You can select Automatically save a version on close to ensure that the document is versioned each time you close it.
- In the Save As dialog box, click the Tools button and choose Save Version.
The difference between the Versions feature and saving "backups" using the automatic backup feature, or by choosing Save As and giving the file a new name is that, with the Version feature, all versions are stored within a single file. The document actually contains each of its versions in a single package.
To access a previous version, choose File ? Versions, select a version and click Open.
