after making zip archive i have some files with strange names that i couldnt open

[mod9]

Binary package hint: file-roller

[/media/disk/zi81nOv8]
  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: /media/disk/zi81nOv8 may be a plain executable, not an archive
zipinfo: cannot find zipfile directory in one of /media/disk/zi81nOv8 or
          /media/disk/zi81nOv8.zip, and cannot find /media/disk/zi81nOv8.ZIP, period.
