Note: Maximum File Size

The maximum file size is limited to 32 MB for the total document text only and does not include graphics regardless of how the graphic is inserted (Link to file, Save with document, or Float over text) into the document. Therefore, if the file contains graphics, the maximum file size can be larger than 32 MB. Note: This maximum file size is different from previous versions of Word.
