Hi ezeemon,
okay... And what's your question?
Do you want to let the user choose the path? Then use "File Dialog" (File IO -> Advanced) with proper settings (files/dirs, new/existing etc.) Or don't wire a path to a file open function - it will open the file dialog on it's own...
Best regards,
GerdW
