- All Implemented Interfaces:
    ZipExtraField

      public class X000A_NTFS
      extends Object
      implements ZipExtraField

  NTFS extra field that was thought to store various attributes but in reality only stores timestamps.

          4.5.5 -NTFS Extra Field (0x000a):

             The following is the layout of the NTFS attributes
             "extra" block. (Note: At this time the Mtime, Atime
             and Ctime values MAY be used on any WIN32 system.)

             Note: all fields stored in Intel low-byte/high-byte order.

               Value      Size       Description
               -----      ----       -----------
       (NTFS)  0x000a     2 bytes    Tag for this "extra" block type
               TSize      2 bytes    Size of the total "extra" block
               Reserved   4 bytes    Reserved for future use
               Tag1       2 bytes    NTFS attribute tag value #1
               Size1      2 bytes    Size of attribute #1, in bytes
               (var)      Size1      Attribute #1 data
                .
                .
                .
                TagN       2 bytes    NTFS attribute tag value #N
                SizeN      2 bytes    Size of attribute #N, in bytes
                (var)      SizeN      Attribute #N data

              For NTFS, values for Tag1 through TagN are as follows:
              (currently only one set of attributes is defined for NTFS)

                -----      ----       -----------
