Parallel implementations offer improved speeds by using multiple CPU cores.Uses LZMA, default for GNU coreutils and kernel archive files. Written in C, focused on compression and decompression speed.Ĭan be multithreaded, though the lz4 is not. Improved version of rzip, uses multiple algorithms. Pigz, bgzip(1) (part of htslib AUR), crabz AUR, python-rapidgzip AUR These compression programs implement their own file format. While BSD tar recognizes compression formats based on the format, GNU tar only guesses based on the file extension. When creating archives both support the -a switch to automatically filter the created archive through the right compression program based on the file extension. Only BSD tar supports lz4 natively (but GNU tar can do an equivalent with -use-compress-program=lz4/ -Ilz4). Tip: Both GNU and BSD tar automatically do decompression delegation for bzip2, compress, gzip, lzip, lzma, lzop, zstd, and xz compressed archives. Today only used for creating static library files.įile archiver via stdin/stdout, supports cpio and tar formats.Īrchiver to backup large live filesystems, takes care of hard links, extended attributes, sparse files and inode types. Implementation of tar and cpio that also offers a library. Of course there are also tools that do both, which tend to additionally offer encryption, error detection and recovery.Ĭore utility for manipulating the ubiquitous tar archives (tarballs), which are used by pacman and the AUR. These tools are often used in sequence by firstly creating an archive file and then compressing it. A compression tool compresses and decompresses data, e.g.A file archiver combines several files into one archive file, e.g.The full list of supported archives includes bzip2, gzip, lzma, lzw, xz, and Zstandard formats, each one often used to compress tar archives used by Linux.The traditional Unix archiving and compression tools are separated according to the Unix philosophy: Instead, these formats and more will arrive as part of a second wave of ChromeOS’s new archive support, planned for version 104 in August. That said, in most cases, those tar files will be compressed further into a format such as “.tar.gz” or “.tar.xz” neither of which are supported by ChromeOS today. You’ll still see tar files being used on Linux today, most often when distributing software. Lastly, for Linux enthusiasts, ChromeOS has also enabled support for tar files - short for “tape archive,” a format that dates back to 1979. Notably, some ISO files are not supported, specifically those in the UDF format. While disc drives have fallen out of favor in recent years - for example, you can’t buy a Chromebook that has a CD/DVD drive - the format still sees use for archival and for operating system use.Īs a test, we were able to download an ISO of the latest version of Ubuntu and rapidly access the files within. These files were often used as a basis for burning a new disc containing the same data. ![]() These files can now be opened easily on ChromeOS, which likely didn’t take much work as they’re simply renamed zip archives.ĬhromeOS can now also correctly mount ISO files, which represent the data that would be written to a disc, such as a CD, DVD, or Blu-Ray. ![]() ![]() ![]() While the Chrome Web Store aims to make installing new extensions seamless, under the hood it’s really distributing these crx files with the extension’s code. Notably, password-protected 7z files are not yet supported.Īnyone who has ever developed a Chrome Extension should recognize the crx format. Some people choose to use 7z files instead of standard zip archives to create smaller files for sharing and storing. First up, there’s new support in ChromeOS for the 7z format, which is an archive format originating in the 7-Zip program. In its initial form, it’s now possible to open three new archive formats on your Chromebook. Nearly a year later, that feature has now begun to arrive, starting with May’s update to ChromeOS 101. Last July, we were first to report that Google was working on a new way for the Files app in ChromeOS to be able to view and extract files from quite a few different formats. ChromeOS is now more powerful for managing files, with new support for archive formats like 7z, iso, and tar - with more on the way.
