The Extract PDF Page Range activity is used to extract a specific set of pages from a PDF file and save them as a new PDF file1. The OutputFileName argument is required and specifies the path and name of the new PDF file1. The Range argument accepts complex range values or "All" to indicate which pages to extract12. For example, "1-3,5,7-9" will extract pages 1 to 3, 5, and 7 to 92. The PageCount argument outputs the number of pages in the original PDF file, not the extracted pages1. Password-protected PDF files can be processed with this activity by using the Password argument to provide the password1.
