.z file compression

Hello,

I have a .z file which i understand to be UNIX.

I'm on PC (no UNIX boxes) and have tried many different unzipping programs to extract this .z file, but only PicoZip has allowed me to view what is inside (telling me, i think, that it's not corrupt), but i have not been able to extract it from there, either.

Anyone able to extract this file and send me the contents as a .zip or .rar file or as individual files? It is here attached, but I had to change the extension to ".zip" to upload it, so don't forget to change it back to ".z" if necessary.

Thanks so much for any help...

It is so very, very not a UNIX file. It is a strange format called an "InstallShield Z archive", probably InstallShield 3.x. The only thing I know of that might even touch it is a Windows program called Universal Extractor.

arunk, did you think I was joking?

Code:
tyler@mecgentoo ~ $ gunzip RolandJV1010.zip
gunzip: RolandJV1010.zip: unknown suffix -- ignored

tyler@mecgentoo ~ $ mv RolandJV1010.zip RolandJV1010.gz
tyler@mecgentoo ~ $ gunzip RolandJV1010.gz

gunzip: RolandJV1010.gz: not in gzip format

tyler@mecgentoo ~ $ unzip RolandJV1010.gz
Archive:  RolandJV1010.gz
  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:  RolandJV1010.gz may be a plain executable, not an archive
unzip:  cannot find zipfile directory in one of RolandJV1010.gz or
        RolandJV1010.gz.zip, and cannot find RolandJV1010.gz.ZIP, period.

tyler@mecgentoo ~ $ file RolandJV1010.gz
RolandJV1010.gz: InstallShield Z archive Data
tyler@mecgentoo ~ $
This is not a gzip file, not a zip file, and definitely not any archive format that UNIX is equipped to understand.
