7-Zip 9.15 beta portable

7-Zip is an open source file archiver with a high compression ratio. Its primary compression method is LZMA, which often compresses better than RAR. Originally developed for Windows, other projects like p7zip and PeaZip made this format also usable on Linux and Mac OS.

PortableApps released a portable version of the latest stable 7-Zip version, 4.65, released in February 2009. Since then, a lot of development has been made but only betas were released yet, thus PortableApps didn’t make new versions. So, as usual, I made a “home-made” package using PortableApps’s current launcher combined with the latest 7-Zip version, and here it is, 7-Zip 9.15 beta portable, as a zip so you’re not screwed if your network blocks EXEs and you can open it simply with Windows Explorer if you don’t have better.

The main interest of the 9.x beta series is the new compression algorithm LZMA2, which compresses quite faster than LZMA if heavily multithreaded, and which generates close to zero overhead when used on uncompressible data.

    OK, I looked for a way to pass you a message, I guess this is it.

    While I appreciate your work on Scroogle, I decided it’s not for me.

    However, there’s no way to uninstall the add on!

    Please advise!

    It’s actually not really an add-on but just another search engine. I don’t know why Mozilla wants this to be in the add-on category… Anyway, since it’s just a search engine, you manage it just like other search engines: push the button at the left of the search engine field, it opens the list of available search engines. Then at the bottom you have “Manage search engines”. From this menu you can move up and down your engines, as well as remove them 🙂
