 Well.....
PKzip and PKunzip don't support the LZW format either.
That's because LZW is not a compression format for archiving utilities.
It's the compression format for GIF graphics files.
And yes, Unisys/Compuserve owns the rights to GIF/LZW

Not many people realize that the LZW algorithm can also used for TIFF and JPG

For an in-depth explanation.....

Oh, and the term is "floppy disk spanning". ;-)
