The string or path that you want to evaluate. This input can also be any data type that contains only strings or paths, such as an array of strings or paths or a cluster of strings or paths.

datatype_icon

A Boolean specifying whether the input is empty.

This value is of the same data type structure as string or path. For example, if string or path is an array, empty? is also an array.
