The FILE_CHANGED function is provided to work with the external data property type. It evaluates the file referenced by such a property and returns true if the file has been modified since it was downloaded to the client device or attached locally. Though the data type of this function’s single parameter is string, the function expects an external data property and will return false for any other value provided.

Though the data type of this parameter is string, the intended usage of this function is that this parameter is an external data property. Specifying any other string value for this parameter will result in the function always returning false.
