See also the function “TrFile_CreateFile” to create a new empty file.
macOS only. Note that Creator codes and FileTypes are deprecated in macOS, but still supported by the plug-in. Ignored on Windows.
Starting from v3.0.5: if you use “” as creator no creator is used for newly created files.


We assume that in your FileMaker file the following fields are defined:

  gErrorCode		Global, number
  gFilePath		Global, text
  textField		text

gFilePath should contain the path to an existing file, for example “D:\Hello.TXT” (Windows) or “Disk1:Hello” (Mac). TextField contains the text you want to write. In a script add the following scriptsteps:

Set Field [ gErrorCode ; TrFile_SetDefaultFileSpec ( gFilePath ) ]
Set Field [ gErrorCode ; TrFile_SetDefaultCreator ( "ttxt" ) ]
Set Field [ gErrorCode ; TrFile_SetDefaultType ( "TEXT" ) ]
Set Field [ gErrorCode ; TrFile_SetContents ( "-Encoding=ASCII_Windows" ; textField ) ]

This will set the default file to your file with a SimpleText FileType and Creator. Then the text is written to the file.
