unzip的时候，死活解不开，路径没有问题啊。
Archive:  20070802.Z
  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.
unzip:  cannot find zipfile directory in one of 20070802.Z or
        20070802.Z.zip, and cannot find 20070802.Z.ZIP, period.

哪位兄弟遇见过

try uncompress

估计是你的操作失误。用啥压缩的就用啥解压缩！
