NSFileManager(FileTest)

Extends Class: NSFileManager
Declared In: FileTest.h

Discussion

The FileTest category adds short methods that mimic the Unix shell file test operators like -x and -d. These methods are implemented with the default file manager, which is available as filem.

The access tests (test_r:, test_w:, and test_x:) use only standard Unix user and group ids. Access control lists are not considered.
