Path controls do not have the same functionality on Mobile targets as on Windows. Mobile applications translate path controls and indicators into string controls and indicators and treat the data as strings, which means the Browse button in the path control is not visible on the target.
Use paths only as inputs to the File I/O functions and to refer to the location to which the application transfers the file when you sync to a host computer. Use the File Dialog Express VI to obtain the path from a user in a Mobile application.
