*Well: ZIP 3.1 Beta also "stores" the file:*

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

         Connect request received at  6-DEC-2009 17:41:11.89
             from remote process NETBCK::"0=SYSTEM"
             for object "ZIPPER"

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

This is Zip 3.1b BETA (Apr 9th 2009), by Info-ZIP.
   adding: -

         (in=1239645) (out=1239645) (stored 0%)
total bytes=1239645, compressed=1239645 -> 0% savings
Get RMS defaults.  getjpi sts = %x00000001.
                Default: deq =      0, mbc =   0, mbf =   0.
Open callback.  ID = 1, deq =  16384, mbc = 127, mbf =   2.
Archive:  SYS$SYSROOT:[SYSMGR]REMOTE.ZIP;1
  Length   Method    Size  Ratio   Date   Time   CRC-32    Name
--------  ------  ------- -----   ----   ----   ------    ----
  1239645  Stored  1239645   0%  01-01-80 00:00  ebc2993b  -
--------          -------  ---                            -------
  1239645          1239645   0%                            1 file

*And then, after modifying the name in the archive, I can extract the 
save set. It's header appeard to be correct (after setting file 
attributes), but after the first block or so it falls apart:*


$ pipe zipnote -w REMOTE.ZIP < remote.zn
$ unz -v remote
