There are many ways to add Adobe PDF files to a PDF Creator Plus project:
•Dragging and dropping a PDF onto the builder application.
•From the application menu, File -> Import PDF or Other File
•In the context menu of the Thumbnails tab background, use the Append File... option to add a PDF to the end of the current collection of pages
•On the context menu for a selected page in the Thumbnails tab, use Import File to add a PDF Before or After the selected page, or to Append the file to the end of the current collection of pages.
•Printed to the PDF Creator Plus 8 printer.
All of these actions add a copy of the pages in the PDF into the builder application. The original file is left untouched.
If the PDF file is an Adobe® LiveCycle PDF it cannot be added directly. In the case of a LiveCycle PDF, the pages can only be added by printing the PDF file.
Password protected PDF files
If a PDF File is password protected, you will be prompted to supply the password in order to open the file to add the pages.
Adding pages using drag and drop
When the PDF Creator Plus build application is open, Adobe®PDF files can be added by selecting a PDF, or multiple PDF files, in a File Explorer window and dragging them over the PDF Creator Plus builder application window. Dropped files are always appended to the end of any loaded pages. When dropping a group of files the order in which the files are received is determined by the underlying file system and cannot be guaranteed.
Importing pages
Pages can be added by importing the PDF into an existing PDF Creator Plus project. This brings in a copy of the pages and leaves the original PDF file untouched.
1.From the File menu, select the Import PF or Other File… menu item, or click the Import 
button on the Standard toolbar.
2.In the Import File dialog that appears, browse to folder that contains the Adobe® PDF file you wish to import. You can use the filter drop down on the right to show just the PDF files for easier selection.
3.The Import dialog also allows you to choose where to insert the pages into your project. The default is to Append to end. If there are already pages in the project you can choose to insert the new pages Before or After a particular page in the project.
4.Once you have chosen your file and where to add the pages, click the Open button to import the pages into your current project.
Appending pages from the thumbnail view
Add pages to the end of the project using the Append File... option in the Thumbnails tab. The context menu appears when right-clicking on the background area of the thumbnails panel, not on a page.
Inserting pages from the thumbnail view
Insert pages before or after the currently selected page using the Import File -> Before... and Import File -> After... options in the thumbnail page context menu. Pages can be appended to the end of all the pages using the Import File -> Append... option. Right-click on the page to show the menu.
