Uniform Standard Tape Archive Format File

Archive file created using USTAR formatting, which defines a small extension to the .TAR format; stores a collection of files in an uncompressed format; extends the TAR specification with a longer header definition, support for longer archived filenames, and support for more information about each file in the archive.
