Portable 7-Zip 23.01 Final Multilingual
7-Zip is a file archiver with a high compression ratio. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. High compression ratio in new 7z format with LZMA compression. Supported formats – Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR. Unpacking only: 7z, ZIP, RAR, GZIP, GZ, BZIP2, BZ2, TAR, CAB, ISO, ARJ, LZH, LHA, CHM, MSI, WIM, Z, CPIO, RPM, DEB, CPIO, DMG, FAT, HFS, LZMA, NTFS, SPLIT, SWM, TAZ, TBZ, TBZ2, TGZ, TPZ, VHD, XAR, XZ, Z and NSIS. For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip. Self-extracting capability for 7z format. Integration with Windows Shell. Powerful File Manager. Localizations for 70 languages.
With today’s fast broadband rates, sending large files, or a large number of smaller files, via the Internet is easier than ever. Windows includes a compression program that allows you to zip files together and compress them into a single package. The problem is that it isn’t particularly good.
7-Zip is a superior alternative. Here are five reasons why you should be 7z-ing your files rather than zipping them up…
1. A dedicated file compression tool allows you to have more control over how you archive your files, the compression ratio, the container format, and whether or not you apply security layers. (7-Zip, for example, enables 256-bit AES encryption at the bank level).
2. The widely used ZIP format is inefficient in comparison to newer formats.
While 7-Zip supports ZIP files, the software’s native 7z format, which combines powerful LZMA and LZMA2 compression algorithms for enhanced file-squashing, yields better results. According to the creators of 7-Zip, 7z is often 30 percent to 70 percent more efficient than the original ZIP format.
3. That isn’t to state that 7-Zip is just compatible with 7z and ZIP files. It can also compress files using the XZ, BZIP2, GZIP, TAR, and WIM formats.
4. While 7-Zip’s archiving abilities are amazing, it can inflate far more file types than it can deflate, so you should be able to open the vast majority of archive files you get. ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR, and Z are among the formats supported.
5. Have you noticed that RAR is supported? 7-Zip also supports the WinRAR file format, which is one of its main competitors.
That’s all there is to ZIP and RAR. There’s no need to download additional software to extract data from those two file types.
The main features of 7-Zip:
- High compression ratio in 7z format with LZMA and LZMA2 compression
- Supported formats:
- Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM
- Unpacking only: AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM, SquashFS, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR and Z.
- For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip
- Strong AES-256 encryption in 7z and ZIP formats
- Self-extracting capability for 7z format
- Integration with Windows Shell
- Powerful File Manager
- Powerful command line version
- Plugin for FAR Manager
- Localizations for 87 languages
- 7-Zip works in Windows 11 / 10 / 8 / 7 / Vista / XP / 2012 / 2008 / 2003 / 2000 / NT. There is a port of the command line version to Linux/Unix.
7z has an open architecture, so it can support any new compression method, too. The following methods currently are integrated into 7z:
- LZMA – Improved and optimized version of LZ77 algorithm
- PPMD – Dmitry Shkarin’s PPMdH with small changes
- BCJ – Converter for 32-bit x86 executables
- BCJ2 – Converter for 32-bit x86 executables
- BZip2 – Standard BWT algorithm
- Deflate – Standard LZ77-based algorithm
LZMA is the default and general compression method of 7z format. The main features of LZMA are:
- High compression ratio
- Variable dictionary size (up to 4 GB)
- Compression speed: about 1 MB/s on 2 GHz CPU
- Decompression speed: about 10-20 MB/s on 2 GHz CPU
- Small memory requirement for decompression (depend from dictionary size)
- Small code size for decompression: about 5 KB
- Supports multi-threading and P4’s hyper-threading
- 7-Zip now can unpack DMG archives that use LZFSE compression method. - 7-Zip now doesn't allow update operation for archives that have read-only attribute. - The BUG was fixed extracting from tar with -si switch didn't set timestamps for directories. - Some bugs were fixed.
