What is a .TAR file?
A TAR file is a type of archive file that groups multiple files into one, preserving the directory structure. It does not compress the data itself, but can be combined with compression formats like GZ or XZ.
Background
The TAR format, short for Tape Archive, originated in the early days of Unix systems to facilitate the storage of large amounts of data on magnetic tape. It is widely used in Unix and Linux distributions to package software and backup data. While TAR itself does not compress files, it is often used in conjunction with compression formats like GZ (gzip) or BZ2 (bzip2) to create compressed archives such as .tar.gz or .tar.bz2. This combination allows for both the bundling of files and the reduction of storage space. Due to its simplicity and effectiveness, TAR remains a popular choice for developers and system administrators.
