I must be old. :) Apparently Mac extensions were added to the spec --
-ZipIt Macintosh Extra Field (long) (0x2605):
The following is the layout of the ZipIt extra block
for Macintosh. The local-header and central-header versions
are identical. This block must be present if the file is
stored MacBinary-encoded and it should not be used if the file
is not stored MacBinary-encoded.
Value Size Description
----- ---- -----------
(Mac2) 0x2605 Short tag for this extra block type
TSize Short total data size for this block
"ZPIT" beLong extra-field signature
FnLen Byte length of FileName
FileName variable full Macintosh filename
FileType Byte four-byte Mac file type string
Creator Byte four-byte Mac creator string
Which Mac Zip tools use those?
And do any of the Win Zip tools allows you to define the values of those
fields for moving files cross-platform?
