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 - Delete Pages Menu
Selecting "Extract Pages..." will open the following window:
Win2PDF Desktop - Delete Pages
Enter a page range to delete pages from the document. The total number of pages in the document are listed. To delete a single page, enter the same page number in both boxes. If the document only contains one page, the delete pages item is not available.
