Returns OK or error.


Asks app to open a given file.
This happens asynchronously, so we have no idea if it works or not.
FileMaker may show error dialogs.
This call must be last in a script as you can’t open a file while a script is running, the file should open when the script is done. You can use FM.RunScriptLater to run a script in a few seconds to follow up. There you can check with window functions and see if there is a new window in front.

See also Files.Launch and Files.LaunchFile.

This function requires a native path. Use Path.FileMakerPathToNativePath to convert a FileMaker path to a native path if required. If you like to have the user choose the path, you can use FileDialog functions.
