What is a TAR file?
Tar archive created by tar, a Unix-based utility used to package files together; contains multiple files stored in an uncompressed format; commonly compressed into a .GZ file using GNU Zip compression.
NOTE: A filename with the ".tar.gz" multiple extension is a TAR archive that has been compressed with GNU Zip compression. These "tarballs" can also be seen with the .TGZ extension.
