Trying to install 1000base-t adapter and Im not linux literate, what does?

All the files are in .gz format. On receiving them, you need to

gunzip file.ps.gz

which will uncompress them into postscript files. Some of the file is in the form file.tar.gz, on uncompressing you need to

tar xvf file.tar

to extract the postscript files.
