Hey folks, not sure if this has been mentioned before or not...
I scan all of my packing lists into the documents section. After scanning I name the entry with a PO number and the company name. Upon exporting the document to a PDF, when asked for the filename I would like to name it, I entered amazon.com . After exporting the PDF, the extension PDF is not inserted after the .com I wanted to name the file, and when it was done exporting, instead of opening the file in Acrobat Reader, it opened it in a DOS window thinking it was a program with the file extension .com
Nifty!
