Maybe not directly, because I think the FileMaker command for open in AppleScript is only to open database files.
Is there a FileMaker script action which will open (possibly import instead of open) a PDF/Excel file? AppleScript can trigger a FileMaker script, trigger an Open command, or even an Import command as tho you have selected those commands from a FileMaker menu. How is opening a PDF or Excel file with FileMaker done with PC:mad:? JavaScript? A FileMaker option that isn’t in FileMaker for Mac?
I would say that the best option would be to use a FileMaker script that exports the document to the temporary items
path to temporary items
and then auto opens the pdf. This way you are still self containing the pdf within the database and upon restart/login the temp directory should be cleared so you don’t have to worry about removing copies yourself
