GNUTAR - GNU Tar Archive is a file extension that is used for anything that is created and saved in the GNU .TAR format. This extension will help you keep all of your files properly organized and keep all of the alike files together.
This is a relatively handy extension because it properly stores a collection of uncompressed files. Sometimes they may be compressed in a .TGZ or even a .TAR.GZ file which then will use a gzip compression. You will need to make yourself aware of this so you know what to expect upon installation of this wonderful extension.
These types of files are seen more commonly with the .tar extension, so it does come in handy when you need it the most. You can get more information by going online and this file extension is also free of charge. You will learn about opening these files the proper way so you do not end up with any surprises in the end. This extension definitely helps out a lot and gives you that extra boost that you more than willingly need. Again, you can only really benefit from this extension if you save a lot of the .TAR extension files. Otherwise this extension will not really do you any good.
