I am combining multiple files into one PDF, is there a way to save file combine as a project?

I think this tool does it: http://www.coolutils.com/PDFCombinePro. There's an option to download a free trial copy, so you may check it out.

Hi bmercado78,

After combining the PDF files it becomes a single PDF, any changes implemented will be on that combined file. You wont be able to go back & edit what files are being combined.
