[TriLUG] Archive Manager Could not Open Zipped file

[Bill Chan]

I used the command "zip -r * /home/bill/Projects/Oct" to zip up files in
a directory. A .zip extension was added to all the files in that
directory after the command was executed. However, when I used the
Archive Manager to open any of the zipped file, I got this "An error
occurred while loading the archive." error message.
The Command Line Output message is as follows:
[/home/bill/Projects/Oct/20051003/print_06.tif.zip]
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
note:  /home/bill/Projects/Oct/20051003/print_06.tif.zip may be a plain
executable, not an archive
unzip:  cannot find zipfile directory in one
of /home/bill/Projects/Oct/20051003/print_06.tif.zip or
        /home/bill/Projects/Oct/20051003/print_06.tif.zip.zip, and
cannot find /home/bill/Projects/Oct/20051003/print_06.tif.zip.ZIP,
period.

Now I cannot access to any of these file. Can someone help me to recover
these files? I'm trying to move from Windows to Linux, it seems that I'm
getting myself more troubles.

TIA,
