MLISTPermissions is a string property that represents permissions assigned for the file or directory on the remote file system. MLISTPermissions contains any values found when the directory listing parser handles the "perm" keyword in the Facts for the collection item. 

For Unix-based remote file systems, MLISTPermissions may also contain values derived from the "UNIX.Mode" fact for the entry, or information derived from the ItemType property. 

The MListPermissions property will normally contain an empty string ('') when the "perm" fact is not used for the file or directory,
