The Authoring screen does not have an edit function for either increasing and decreasing the number of pages of a registered PDF file or Office data.
When you need to change the number of pages, edit the file by using a graphic tool, a PDF editing tool, Office, or some other tool on the PC, and then upload the file again.
The existing file is overwritten when the edited file is uploaded.
Perform the following operation.
1. Click the “Update Content” button or the content name corresponding to the relevant content on the Contents List screen.
2. Click the “Changed” button of the PDF (Office) Modification item and then select the relevant file on the local PC.
3. When you need to save the authored data, check Secure Authored Data (by default, this item is checked).
4. Click the “Confirm” button.
