TARtiedostot

TARtiedostot, or TAR archives, are a common method for bundling multiple files and directories into a single archive file. The name "TAR" originates from the Unix utility "tape archive," which was originally designed to create archives for backup purposes on magnetic tape storage. Over time, TAR has become a widely used format for archiving data across various operating systems, including Linux, macOS, and Windows.

A TAR archive itself does not provide compression, meaning it simply combines files into one container without reducing their size. However, TAR is often used in conjunction with compression utilities like gzip, bzip2, or xz to create compressed archives with extensions such as .tar.gz, .tar.bz2, or .tar.xz. These compressed formats are widely used for software distribution, backups, and file transfers due to their efficiency and compatibility.

The TAR format preserves the original directory structure and file permissions of the archived files, making it useful for maintaining the integrity of file systems. It is also platform-independent, meaning archives created on one system can typically be extracted on another without modification. This cross-platform compatibility has contributed to its enduring popularity in both personal and professional computing environments.

TAR archives are created and extracted using command-line tools, such as the `tar` command in Unix-like systems. For example, to create a TAR archive named `archive.tar` containing all files in the current directory, one would use the command `tar -cvf archive.tar *`. To extract the contents of such an archive, the command `tar -xvf archive.tar` is employed. These commands allow for efficient management of large collections of files while maintaining their structure and metadata.
