In computing, the '''tar file format''' is a type of archive file format: the Tape ["ARchive"] format. These files are produced by the ["Unix"] command tar and were standardized by POSIX.1-1998 and later POSIX.1-2001.

In the Unix philosophy of "one job, one program", it does not support compression directly. If you then want to compress your archive, you use a separate program that is specialised in compression. tar is most commonly used in tandem with an external compression utility such as ["gzip"] or ["bzip2"], since it has no built in data compression facilities. These compression utilities generally only compress a single file, hence the pairing with tar, which can produce a single file from many files.

A Tarball is a commonly used name to refer to an archive file in the tar (Tape Archive) format.

These files are produced by the Unix command ?[[https://en.wikipedia.org/wiki/Tar_(computing).

It is used widely to archive and unarchive files, which means to accumulate a large collection of files into a single archive file (packer), while preserving FileSystem information such as user and group permissions, dates, and ?directory structures.

Tarballs are commonly used to pack source code.

tar itself does not support compression directly. It is most commonly used in tandem with an external compression utility such as ?gzip or ?bzip2. These compression utilities generally only compress a single file, hence the pairing with tar, which can produce a single file from many files.

The MIME type of tar archives isapplication/x-tar
