Mint/Ubuntu install sudo apt install xz-utilsextract/unzip xz tar file tar -xvf userfiles.tar.xzArchive types tar.gz and tar.xz are both compressed tar-files, however, using variations on the compression method. For the user there is no difference when extracting either type of file, with the exception of extraction speed.
