A document may be broken down into sections.  For example, the main document may consist of the first 50 pages, the first attachment may consist of the next 50 pages and subsequent attachments may consist of a similar number of pages until the entire document is included in the entry.  Each section should be labeled correctly.  For example, the main document could be named Brief, the first attachment could be named Brief Part 2 and the second attachment could be named Brief Part 3.  Please remember that not all documents scan the same.  You may be able to scan 150 pages and stay within the 15 mb limit.  Whereas, if a document includes graphs and pictures, you may only be able to scan 60 pages and stay within the 15 mb limit.  To make sure you are within the 15 mb limit, you should check the size of your scanned documents prior to docketing.
