7-Zip是一款开源免费压缩解压软件，7-Zip使用了LZMA与LZMA2算法的7z格式，拥有极高的压缩比，通常使用7-Zip压缩的7z格式能比使用zip格式的压缩文件小30-70%。7-Zip相比流行的WinRAR压缩软件，具有压缩率高的优势，但7-Zip图形界面相对比较简单，也没有压缩文档注释功能。但7-Zip能解开比较多文件格式包，支持格式：
压缩/解压缩：7z, XZ, BZIP2, GZIP, TAR, ZIP, WIM
仅解压缩：ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR, Z
Changes in 7-Zip 9.31 Alpha:
- The BUG in 7-Zip 9.26 alpha - 9.29 alpha versions was fixed.
- These alpha versions could not open non-solid 7z archive, if
- some files were skipped during creation of that archive.
- That problem is also related to 7z archives created in solid mode,
- if each solid block contains no more than one file.
- Note: 7-Zip skips files that were open for writing by another
- application and shows warning in that case.
