ok, so you got a file called .tar or .tar.gz and now you dont know how to open it in your windows xp pc.

well, .tar.gz files are commonly used in linux computers. they are like .zip files.

so if you have a windows pc, you can download wintar and open them

but if you have linux, you shouldn't have a problem opening.

however, if you have linux with only command you can send this command to open it

tar xvfz filename.tar.gz

done
