If you drag a PDF to the Win2PDF Desktop icon, or select a PDF from the open window when launching the Win2PDF Desktop application, the following options will be displayed under the "Pages" menu:
Win2PDF Desktop - Prepend to an Existing PDF
To prepend (add to the beginning of the existing PDF), choose "Prepend to Existing PDF" and click "Continue". A file open Window will be displayed allowing you to select the existing PDF to prepend to.
This is also available using the APPEND command line.
