Authors/Port authors:

This is an archiving utility with better compression ratios than many other archivers.

This software is distributed in two modes:
  • as compressed package that you have to download and manually install; if prerequisites are required, you will have to manually install them too;
  • as RPM package; you can install it using your favorite rpm package manager, that will take care to download and install both the software and its prerequisites.
Choose the installation mode that you prefer. Please note that not all the versions are available in both the installation modes.

Installation with rpm

This program is installable using the rpm package manager. See below for the install string. Required prerequisites are automatically processed by the package manager and, if needed, downloaded and installed.

Thanks for porting 7z-archiver to OS/2. Regarding command-line versions in release of p7zip-16.02-os2-1.zip: It works fine unless drive letters are in use, e.g. "7za.exe l \ArcaOS\Downloads\ArcaOS-5.0.2.iso.7z" is fine, but "7za.exe l C:\ArcaOS\Downloads\ArcaOS-5.0.2.iso.7z" fails by a system error ("Unknown error -2147024872"). Thus, it works for relative paths only! Can you please fix that? Thanks a lot in advance.
