# Open File by the OS

This function is used to open a file by the OS's default application for the files of that type. For example, files with a .txt extension will typically be opened by TextEdit.

The path may contain any of the escape sequences described in Escape Sequences. At runtime, the path to the file must be absolute (/) or relative to the home folder (~/).

The action test state will be set to true if the open succeeded, otherwise false.
