After working the command, you may discover the newly created TEST.tar.gz. The tar portion of the extension means the file is a tar archive and the gz signifies it has been compressed. 

You can then decompress that new file with the command tar -xvzf TEST.tar.gz. 

For those who wished to view the information inside that archive (with out decompressing and extracting), you can problem the widespread tar -ztvf TEST.tar.gz and tar would checklist out the contents for you.
