A tar file, otherwise known as a Tape Archive file, is a type of data container which stores multiple files in an aggregate format. This enables the user to create a single compressed file containing many distinct files, allowing for efficient storage and data manipulation. The tar format is composed of several components including header blocks, archived files and end-of-file blocks. Each header block contains information about the archived file such as its name, size and permission flags. The data set is stored in the form of a single 'tarball', which is then compressed using various algorithms such as gzip, bzip2 and xz.What is a tar file?UnZiper is an incredibly helpful and easy-to-use online tool that makes it possible to extract, compress, or convert compressed files in an instant.
