![]() So we’ve demonstrated that xz does indeed create much smaller archives than gzip. #Xz file extension archiveBut at 70 seconds, xz also took nearly 18 times as long! Compression levels six and beyond hugely increased the compression time for a negligible 1% reduction in archive size With compression level 5, xz produced the smallest archive at 29 MB, which was 69% smaller than pig z.xz used compression level 1 out of 9 for this In the same 4 seconds, xz compressed the file to just 48 MB, which was 49% smaller than pigz.Higher compression levels didn’t produce meaningfully smaller archives At compression level 7 out of 9, pigz compressed the 818 MB CSV file down to 95 MB in 4 seconds.pigz does this by default, xz because of the -T0 option xz files on my Linux system. Both archiving tools saturated the CPU in our tests. XZ files are XZipped archive files, this format is a high-ratio compression algorithm based on the LZMA algorithm.We compared xz to pigz, a gzip implementation that uses multithreading for faster compression and decompression. To test this claim, we used the same 818 MB CSV file, and the same computer with six CPU cores and hyperthreading, as we used to test gzip in Linux. Previously, we stated that xz creates smaller archives than gzip. It is extremely important to make a backup copy of the registry before making any changes to it. Confirm by clicking OK or by using the ENTER key. XZ extension you are interested in by typing it in the search window. Unlike xz, tar doesn’t delete the archive file after the extraction is completeĥ. Using the keyboard shortcut ctr + F or the Edit menu and by selecting 'Find' look for the.Because of the v option, tar shows which files are extracted from the archive File extension: XZ: File type: compressed archive file: What is an XZ file XZ files mostly belong to XZ Utils by The Tukaani Project.tar does this automatically by inspecting the file and detecting the xz compression ![]() We don’t have to tell tar to decompress with xz.XZ file, which is associated with the 1 file types. It also happens that the file extension is associated with a number of different file formats. We decompress the file and extract its content into the current directory The file extension allows the operating system or the user of the device to recognize its format and use the appropriate program that allows to run it.Please note that we removed the J option here because –use-compress-program already sets the compression program.ĭecompressing a tar archive with xz is also a single step and identical to gzip (except for the different file extension): tar xvf ![]() Here, we specify the minimum compression level 1: tar cvf -use-compress-program='xz -1' *.csv We use this option to set the compression level, too. Tar allows setting the compression program through the –use-compress-program option. Which xz compression level does tar pick? It depends on our version of tar, but it probably is the default compression level 6.
