A Tarball is a commonly used name to refer to an archive file in the tar (Tape Archive) format.
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
- .tar.gz or .tgz (only when compressed by gzip)
- .tar.bz2 or .tbz (only when compressed by bzip2)
