Params path is a legal path name to the file to which you wish to append text.
Action Writes lineString and a carriage return at the end of the file identified by path.
Returns True if the write is successful, false if the file doesn't exist or if path identifies a folder. In this example, the file you want to write to must have been previously created. If the file cannot be opened for writing because, for example, another application already has it open, or the file does not exist, an error will result. If the disk is full or becomes full during the file.writeLine operation, an error will result. However, if many write operations are to be performed, calling file.open beforehand and file.close afterwards will improve performance.
