7-Zip, the popular open-source application for compressing files, just received a new update. The new 7-Zip 25.0 release is still the same tool you know and love, but with some helpful performance improvements and bug fixes.
If you’ve never used it before, 7-Zip is a fantastic tool for opening or creating compressed file packages—most commonly ZIP files. Besides its own 7z format, it can also open files in XZ, BZIP2, GZIP, TAR, ZIP and WIM formats, as well as disk images like VHD and ISO files. It also has helpful integrations with the Windows File Manager and PowerShell.
The latest 7-Zip 25.0 update adds the ability to use more than 64 CPU threads for compressing ZIP, 7Z, and XZ archives, and when running 7-Zip’s own internal benchmark. Most people don’t have a processor with that many threads, but if you have a CPU like recent AMD Threadripper models, you can now unzip your downloads at the speed of light.
There are also some helpful performance improvements for working with BZIP2, ZIP, and GZ files, and some other updates. The full changelog is below.
What’s New in 7-Zip 25.0:
- 7-Zip for Windows can now use more than 64 CPU threads for compression to zip/7z/xz archives and for the 7-Zip benchmark. If there are more than one processor group in Windows (on systems with more than 64 cpu threads), 7-Zip distributes running CPU threads across different processor groups.
- bzip2 compression speed was increased by 15–40%.
- deflate (zip/gz) compression speed was increased by 1–3%.
- improved support for zip, cpio and fat archives.
- fixed some bugs and vulnerabilities.
This isn’t a significant update by any means, but it still works well for the intended purpose of working with compressed and archived packages. The desktop graphical application still has a utilitarian interface without the modern Windows 11 frosted glass aesthetic, and that’s probably how most people would prefer it.
