Everything to do this is availabe in script engine. You could create a simple script along the lines of:
Save a Copy as - specify output to a temp folder somewhere
Send Mail - Attach file to email, can use email client or automatically using smtp server.
If you use SMTP server you can optionally Set Error Capture to on and use Get ( LastError ) to see if it was sent successfully.
Tie your button to the script and you'll be all set.
Also, keep in mind that depending on the size of the file, it may or may not be able to be sent via email.
Thanks. That worked great. I knew there had to be a simple solution.
Unless they are heavily loaded with stored images, FileMaker Files almost invariably zip to 35-45% of their native size. Which is handy...
And it is possible to include command line code to achive this within a script.
