7-Zip v23.00 Download




Here you can download the latest version of 7-Zip. 7-Zip is a file archiver with a high compression ratio. You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip.
7-Zip is a file archiver with a high compression ratio for ZIP and GZIP formats, which is between 2 to 10% better than its peers, depending on the exact data tested. And 7-Zip boosts its very own 7z archive format that also offers a significantly higher compression ratio than its peers—up to 40% higher! This is mainly because 7-Zip uses LZMA and LZMA2 compression, with strong compression settings and dictionary sizes, to slow but vastly improve density. If a zip tool gains its appeal from its ability to efficiently compress files, then 7-Zip proves it has a little bit o’ magic.
7-Zip
After you effortlessly download and launch 7-Zip, you’ll quickly discover its simple and easy to navigate interface. The main toolbar contains 7-Zip’s most used features and there are several menus that allow you to dig deeper within. For example, the Extract button lets you easily browse for or accept the default destination directory for your file, while the View menu contains a Folder History, and the Favorites menu lets you save up to ten folders. 7-Zip also integrates with the Windows Explorer menus, displaying archive files as folders and providing a toolbar with drag-and-drop functions. You can also alternate between a single or dual-pane view.
Product Details
What's new:
- 7-Zip now can extract APFS (Apple File System) images that can be used in DMG files.
- 7-Zip now can create TAR archives in POSIX (pax) tar format with the switches
- -ttar -mm=pax or -ttar -mm=posix
- 7-Zip now can store additional file timestamps with high precision (1 ns in Linux) in tar/pax archives with the following switches:
- -ttar -mm=pax -mtp=3 -mtc -mta
- New switches for Linux version for TAR archives:
- -snoi : store owner/group ids in archive or set owner/group ids from archive to extracted files.
- -snon : store owner/group names in archive
- New -snz switch to propagate Zone.Identifier stream to extracted files (Windows).
- New option "Propagate Zone.Id stream" in Tools/Options/7-Zip menu.
- New "Options" window in "Add to archive" allows to select what metadata must be included to archive. Also it allows to select new option
- "Do not change source files last access time".
- Some bugs were fixed.

Editor's Note:
What's new: 7-Zip now can use new ARM64 filter for compression to 7z and xz archives. ARM64 filter can increase compression ratio for data containing executable files compiled for ARM64 (AArch64) architecture. Also 7-Zip now parses executable files (that have exe and dll filename extensions) before compressing, and it selects appropriate filter for each parsed file: BCJ or BCJ2 filter for x86 executable files, ARM64 filter for ARM64 executable files. Previous versions by default used x86 filter BCJ or BCJ2 for all exe/dll files. Default section size for BCJ2 filter was changed from 64 MiB to 240 MiB. It can increase compression ratio for executable files larger than 64 MiB. UDF: support was improved. cpio: support for hard links. Some changes and optimizations in WIM creation code. When new 7-Zip creates multivolume archive, 7-Zip keeps in open state only volumes that still can be changed. Previous versions kept all volumes in open state until the end of the archive creation. 7-Zip for Linux and macOS now can reduce the number of simultaneously open files, when 7-Zip opens, extracts or creates multivolume archive. It allows to avoid the failures for cases with big number of volumes, bacause there is a limitation for number of open files allowed for a single program in Linux and macOS. There are optimizations in code for 7-Zip's context menu in Explorer: the speed of preparing of the menu showing was improved for cases when big number of files were selected by external program for context menu that contains 7-Zip menu commands. There are changes in code for the drag-and-drop operations to and from 7-Zip File Manager. And the drag-and-drop operation with right button of mouse now is supported for some cases.

Another reason to upgrade:
The speed for single-thread LZMA/LZMA2 decoding
was increased by 30% in x64 version and by 3% in x86 version.
7-Zip now can use multi-threading for 7z/LZMA2 decoding,
if there are multiple independent data chunks in LZMA2 stream.
7-Zip now can use multi-threading for xz decoding,
if there are multiple blocks in xz stream.
The speed for LZMA/LZMA2 compressing was increased
by 8% for fastest/fast compression levels and
by 3% for normal/maximum compression levels.

You know its not remote code execution if you have to download a file first and open it locally. Whats with the security people these days.
Obviously something like 7-Zip which is not a persistent service of any kind will likely never be affected by Remote Code Execution, since remote hackers cannot interact with it whatsoever - unless you have a web-service that somehow interacts with 7-Zip (to unpack uploaded files, for example), but thats reaching.

One day I discovered Chocolatey:
https://chocolatey.org/
Since that day, updates on free software are no longer a concern.
p.s. - 7-Zip is already updated in the repository - It says version 18.5, and not 18.05 (but it's same thing)
I use PatchMyPC. Real handy and easy.

Nice tool, but that program is a little toy compared to Choco:
"There are 5762 community maintained packages" (currently)
This one is the Windows equivalent of Ubuntu package manager... it can install, uninstall, update software, look for new software in various categories, etc. I a completely different class than that little tool.
Oh, and there is a GUI as well (which I'm using), so I don't mess around with commandline:
