I want to be able to shutdown filemaker and any open db at a given time. Eg At 17:00 close open *.fp7 files and shutdown the application when i am awayfrom the office.

i was thinking along the lines of a "End If" etc.

Can this work?

Not through ScriptMaker scripts, unless some kind of scheduling plug-in is used to activate the script.

However an OS-level script might do the trick - AppleScript or something similar - that is triggered by an OS-level scheduling utility like chron.

Windows XP can have scheduled tasks so create an FMP file that when started it executes the QUIT application script step. All the open files are automatically closed when quitting FMP.

Tell the XP schedule to open your "shut down" file.
