Launch of PeaZip 10.5: A Feature-Rich Cross-Platform Open-Source Archiver

On June 15, 2025, the cross-platform open-source file manager and archive tool PeaZip 10.5 was released. The project’s source code, written in Pascal (using Lazarus/FreePascal, with InnoSetup employed for Windows builds), is available on [GitHub](https://github.com/peazip/PeaZip) under the GNU Lesser General Public License v3.0.

PeaZip 10.5 utilizes Pea 1.25 as the default backend and is compiled with Lazarus 3.4, while still maintaining compatibility with the Lazarus 2.x series. The previous version, PeaZip 9.0, was released in December 2022.

This release includes updated components project_pea and project_peach aimed at optimizing and debugging project-level settings for the Lazarus 3.x series, alongside various internal enhancements that reduce startup time by about 25% and memory usage by 20%.

With the free tool PeaZip, users across Windows, Linux, and Mac can handle a total of 242 file extensions as archives or their variants, such as 7z, ace, arc, bz2, cab, gz, iso, paq, pea, rar, tar, wim, zip, zipx, and many more. The software supports split archives (001, r01, z01, etc.), multiple archive encryption standards, and file hashing. PeaZip is localized in 30 languages.

PeaZip 10.5 incorporates various enhancements to the user interface and command-line interface (CLI), along with fixes for bugs identified in previous versions.

Key changes and additions in PeaZip 10.5 include:

— An updated file manager code that boosts archive browsing performance, improves archive editing, and introduces new features for opening files as archives from other archives, prevents the customized file extension list from launching without confirmation, and allows for hiding or showing hidden files.

— Full access to all file browser icon styles and sizes in macOS, similar to other platforms.

— The ability to explore NTFS alternate data streams in Windows for gathering additional file information, including specialized tools for batch input scanning for Zone.Identifier (Mark of The Web) to detect files from external systems.

— By default, the option to include Zone.Identifier metadata in archives is now enabled for all supported formats (RAR, WIM).

— Improved interface translations, and any assistance in translating PeaZip into new languages and maintaining current localizations is welcomed, as noted [here](https://github.com/peazip/PeaZip-Translations).
