I uploaded some Illustrator files (.ai) to a document library. When I try to open them they open as PDFs. I did check my files type/program association on my computer and .ai files should open with Illustrator. Can anyone clue me in to what SharePoint's issue is with this?There are no mistakes; every result tells you something of value about what you're are trying to accomplish.
