There are a number of reasons for excessive file size, including:
1. Fast Saves: Disable this at on the Save tab of Tools | Options.
2. Preview Picture: Clear the check box on the Summary tab of File |
Properties.
3. Versions (File | Versions): Make sure "Automatically save version on
close" is not turned on.
4. Revisions (Tools | Track Changes):
Highlight Changes: Make sure "Highlight changes on screen" is turned on.
Accept/Reject Changes: If "Accept All" or "Reject All" is available then
revisions are present; accept or reject all changes, then turn Track Changes
off.
5. Embedded True Type fonts (Tools | Options | Save); embedding fonts should
be avoided wherever possible.
6. Embedded graphics: When feasible, it is preferable to link the graphics.
7. Document corruption: See
