XZ file format
| Extension | .xz |
| Category | archives |
| Description | The XZ file format is a lossless compression file format that utilizes the LZMA2 compression algorithm. It is intended to supersede the older LZMA and LZMA2 formats, providing improved compression ratios and quicker decompression speeds. XZ files commonly use the .xz file extension. |
| Technical details | XZ files are created using the xz utility or other compatible programs, and can be opened and extracted using various software applications such as 7-Zip, WinZip, and WinRAR. The format supports compressing multiple files or directories into a single archive, as well as preserving file attributes and permissions. The XZ format is based on a container format that includes the compressed data and metadata about the compression, such as the dictionary size, compression level, and checksums. The container format allows for easy streaming and seeking of compressed data, making it suitable for use in various applications. |
