You can easily group files or directories into one single archive file for convenient distribution, backup or other purposes. Tar is one of the mostly used archive file formats on Unix-like systems. This article will show you how to easily create tar file on Mac Catalina, Mojave, High Sierra and earlier and how to open it.

What is a tar file?

tar file iconA tar file is an archive file created with a software utility of the same name. Compatible with Unix, Unix-like and Microsoft Windows, it is used to collect multiple files into an archive file (which can be called a tarball). The name tar stands for tape archive, and the format was originally developed to save data to tape drives.

It is just a way of collecting data of all kinds (files, directories, etc.) together and doesn’t do any kind of compression. A basic tar file has a .tar extension. You may see files ending with .tar.gz or .tar.bz2. What are they? They are still tar files (or tarballs). In cases like these, files are not only packed but also compressed with compressors such as gzip or bzip2. By doing so, one can create a smaller tar file for more efficient backup or distribution.
