xz is a lossless data compression program and file format which incorporates the LZMA compression algorithm. xz compresses single files as input, and does not bundle multiple files into a single archive. It is therefore common to compress a file that is itself an archive, such as those created by the tar or cpio Unix programs.
Free Zip Wizard is a clean and easy to use free file decompressor that supports ZIP files only. In addition to opening and extracting ZIP files, Free Zip Wizard can create new ZIP files that are password-protected and supports uploading a newly created ZIP file to an FTP server with the built-in FTP client.

On 7-Zip's SourceForge Page you can find a forum, bug reports, and feature request systems. Compression ratio. We compared 7-Zip with WinRAR 5.20.
xz has gained notability for compressing packages in the GNU coreutils project, Debian family of systems deb (file format), openSUSE, Fedora, Arch Linux, Slackware, FreeBSD, Gentoo, GNOME, and TeX Live, as well as being an option to compress a compiled Linux kernel. In December 2013, the Linux kernel maintainers kernel.org announced that they would use xz instead of bzip2 as their compression tool from 2014 on.
txz is short for tar.xz. tar.xz is an archive created with tar and xz utilities; contains one or more files first archived using tar and then compressed using xz compression; compressed using a high compression ratio. Beginning with Slackware 13, TXZ files are used to distribute Slackware Linux packages. They can be opened using various Slackware package management tools, including pkgtool and installpkg. Due to the high compression ratio, TXZ files are typically smaller in size than .TGZ files.
Compared to a few other popular stream compression formats, the .xz format provides a couple of advanced features. At the same time, it has been kept simple enough to be usable in many embedded systems. Here is a summary of the features:
- Streamable: It is always possible to create and decompress .xz files in a pipe; no seeking is required.
- Random-access reading: The data can be split into independently compressed blocks. Every .xz file contains an index of the blocks, which makes limited random-access reading possible when the block size is small enough.
- Multiple filters (algorithms): It is possible to add support for new filters, so no new file format is needed every time a new algorithm has been developed. Developers can use a developer-specific filter ID space for experimental filters.
- Filter chaining: Up to four filters can be chained, which is very similar to piping on the UN*X command line. Chaining can improve compression ratio with some file types. Different filter chain can be used for every independently compressed block.
- Integrity checks: Integrity of all headers is always protected with CRC32. The integrity of the actual data may be verified with CRC32, CRC64, SHA-256, or the check may be omitted completely. It is possible to add new integrity checks in future, but there is no possibility for developer-specific check IDs like there is for filter IDs.
- Concatenation: Just like with .gz and .bz2 files, it is possible to concatenate .xz files as is. The decompressor can decompress a concatenated file as if it was a regular single-stream .xz file.
- Padding: Binary zeros may be appended to .xz files to pad them to fill e.g. a block on a backup tape. The padding needs to be multiple of four bytes, because the size of every valid .xz file is a multiple of four bytes.

You need to install xz-utils. XZ Utils is free general-purpose data compression software with high compression ratio. XZ Utils were written for POSIX-like systems, but also work on some not-so-POSIX systems. XZ Utils are the successor to LZMA Utils. The core of the XZ Utils compression code is based on LZMA SDK, but it has been modified quite a lot to be suitable for XZ Utils. The primary compression algorithm is currently LZMA2, which is used inside the .xz container format. With typical files, XZ Utils create 30% smaller output than gzip and 15% smaller output than bzip2.
XZ Utils consist of several components:

- liblzma is a compression library with API similar to that of zlib.
- xz is a command line tool with syntax similar to that of gzip.
- xzdec is a decompression-only tool smaller than the full-featured xz tool.
- A set of shell scripts (xzgrep, xzdiff, etc.) have been adapted from gzip to ease viewing, grepping, and comparing compressed files.
- Emulation of command line tools of LZMA Utils eases transition from LZMA Utils to XZ Utils.
