Could anyone tell me an easy way to extract tar.gz file without using the terminal or any exclusive archive manager? thanks.
To extract a tar.gz file without the terminal, just simply,1) open the file manager, 2) navigate to the tar.gz file , 3) double click on the file , 4) either copy the contents out of the tar.gz into another folder or just click extract and select the destination from there! And that's it.. You're Done!
If you REALLY don't want to use an archive manager or command line, you could use a python script like the one in this question although admittedly it seems odd that you wouldn't want to use an archive manager but python would be okay.
