Igor Pavlov officially released 7-Zip 26.01 on April 27, 2026, delivering a targeted but impactful update to the world’s most popular open-source file archiver. The headline improvement is support for Linux huge pages — a memory management feature that allocates 2 MB memory pages instead of the standard 4 KB, reducing CPU overhead and enabling noticeably faster compression throughput.

Huge Pages: A Low-Level Win with a High-Impact Result

Huge pages (sometimes called large pages) are an operating system-level feature that allows applications to request larger blocks of contiguous memory. By reducing the number of memory page table entries the CPU must manage, applications doing intensive, sequential memory operations — like compression — can benefit substantially.

10%
Speed increase in compression for 7z, XZ, LZMA, and LZMA2 formats on Linux, when huge pages (2 MB) are available and in use.

It is important to note that this performance gain applies specifically to compression in these formats — not decompression — and only on Linux systems where huge pages are enabled at the OS level. Windows users have had access to a similar feature (large pages) for some time; this update brings Linux into parity.

The affected formats are:

7z XZ LZMA LZMA2 ZIP GZIP BZIP2 TAR RAR (extract only)

New Output Directory Path Switch: -spo[d|c|r]

Version 26.01 also introduces a new command-line switch that gives users finer control over how the output directory path is constructed during archive extraction. The path is generated from the directory specified with the -o{dir_path} option combined with the archive’s filename.

New switch — -spo[d|c|r]
-spod Linux/Posix/macOS only: treats -o{dir_path} as the exact, literal output path. Any asterisk (*) in the path is left unchanged and not substituted.
-spoc Appends the archive’s name to the path specified in -o{dir_path} to form the final output directory path.
-spor Default. Replaces any asterisk (*) in -o{dir_path} with the archive’s filename to build the output path.

This addition brings more predictable and scriptable extraction workflows, particularly useful in automated pipelines where the destination directory structure must be controlled precisely.

Bug Fixes and Availability

As with any maintenance release, 7-Zip 26.01 also includes several unspecified bug fixes. The update is available now as a free download from the official 7-Zip website at 7-zip.org, with builds for 64-bit Windows (x64), 32-bit Windows (x86), Windows ARM64, Linux x86-64, Linux x86, Linux ARM64, Linux ARM, and macOS (ARM64 and x86-64).

7-Zip remains one of the most widely used compression utilities across all platforms. Its core code is licensed under the GNU LGPL, making it freely usable in any environment — including commercial applications — without registration or payment. The software natively supports 7z, ZIP, GZIP, BZIP2, and TAR formats for both compression and extraction, and can decompress a broad array of additional formats including ARJ, CAB, LZH, and RAR.

⚠ Note on Accuracy Some early reports described 7-Zip 26.01’s Linux enhancement as support for “large web pages.” This is incorrect. The feature is huge pages — a Linux kernel memory management feature using 2 MB memory pages. It is unrelated to web browsing or web content. The 10% speed improvement applies to compression operations only, not decompression.
