The dictionary contains entries whose values are the file wrappers and whose keys are the unique filenames that have been assigned to each one. See Accessing File Wrapper Identities in File System Programming Guide for more information about the file-wrapper list structure.
This property may contain
nil if the user modifies the directory after you call
init but before
NSFile has read the contents of the directory. Use the
NSFile reading option to reduce the likelihood of that problem.
This property raises
NSInternal if the file wrapper object is not a directory file wrapper.
