>>273>I couldn't find out how to view or extract these ".gz" files.
.gz (and tar.gz) files can be extracted with 7-zip https://www.7-zip.org
If 7-zip doesn't work, then you should try installing Cygwin https://cygwin.com/
Cygwin is a software package for Windows that emulates an Unix/Linux system.
When you install Cygwin, you have to select a mirror (just pick one, use kernel.org if in doubt) and (at least) select gzip/gunzip when the installer asks which packages to install. Once the installation is complete, you have to open cygwin terminal and navigate to the folder containing the .gz file (use cd to change directory and ls to list its contents. pwd tells where you are currently. If you need more help, check out this site -> https://linuxjourney.com
) Note that you can just copypasta the file into the folder where the Cygwin is installed (there should be a folder called "home" that contains a folder that has same name as your username)
Once you have found the .gz file, you can use gunzip to unzip it. For further info, see https://linux.die.net/man/1/gunzip
