how to open gzip file? I have gzip installed
 

So I have a backup file for my gnucash. The file ends in .gzip. I have tried apt-get install gzip, and get message it is already installed. I can not do on "open with", because gzip does not show up. If I try to open, I get message "archive type not supported".

I'm lost.

Can't open gzip from a terminal.

What should I have installed?

Thanks

"gzip -d <filename>" or if you want a graphical tool you can use Xarchiver.

You can also use tar -z.

Try to change the .gzip extension to .gz. The gzip command accepts files whose name ends with .gz, -gz, .z, -z, _z or .Z. The extension .gzip is wrong (maybe the file has been renamed from the original .gz). Then try to run the gzip -d command again, or gunzip which is equivalent.

Moreover, try the file command on the original .gzip file and feel free to post the output here.
