Tar
- Tape ARchive (filename extension). Tar is a UNIX method of archiving
files, which can also be used by PCs. Tar archives files but does
not compress them, so sometimes .tar files are compressed with
other utilities, which produces extensions like .tar.gz, .tar.Z,
and .tgz. Archive files with the .tar extension can be extracted
in UNIX with tar or on a PC with WinZip or on the Mac with the
program Tar. |

and then gzipped. |
