In computing, tar is a computer software utility for collecting many files into one archive file, often referred to as a tarball, for distribution or backup purposes. The name is derived from "tape archive", as it was originally developed to write data to sequential I/O devices with no file system of their own, such as devices that use magnetic tape.
An implementation of the LZO data compression algorithm. .rz rzip: Unix-like A compression program designed to do particularly well on very large files containing long distance redundancy. .sfark sfArk: Windows compress/decompress- Linux and macOS decompress only A compression program designed to do high compression on SF2 files . .sz
The operating systems the archivers can run on without emulation or compatibility layer. Ubuntu's own GUI Archive manager, for example, can open and create many archive formats (including Rar archives) even to the extent of splitting into parts and encryption and ability to be read by the native program.
Per-file compression with gzip, bzip2, lzo, xz or lzma (as opposed to compressing the whole archive). An individual can choose not to compress already compressed files based on their filename suffix. Fast-extracting of files from anywhere in the archive; Fast listing of archive contents through saving the catalogue of files in the archive
A tar.gz is created by joining the files in tar and then compressing with gzip. In computing, solid compression is a method for data compression of multiple files, wherein all the uncompressed files are concatenated and treated as a single data block. Such an archive is called a solid archive.
.bak, .bk – Bak file various backup formats: some just copies of data files, some in application-specific data backup formats, some formats for general file backup programs; BIN – binary data, often memory dumps of executable code or data to be re-used by the same software that originated it
For example, if the underlying file is a tar archive, this can allow extracting any undamaged files, even if other parts of the archive are damaged. As for the file format, special emphasis has been put on enabling integrity checks by means of an integrated 32-bit checksum for each compressed stream; [ 3 ] this is used in combination with the ...
(User and System) Compressed: Read-only attribute for files compressed using HFS+ Compression In these systems, the chflags and ls commands can be used to change and display file attributes. To change a "user" attribute on a file in 4.4BSD-derived operating systems, the user must be the owner of the file or the superuser; to change a "system ...
