WinRAR now officially supports installation to an external drive (e.g., USB flash drive) and may be used on any computer where this USB flash drive is plugged in. Starting from WinRAR version 5.20 users no longer need to search for dubious portable archiver builds from unknown developers and download them to their computer.
Run the archiver on any computer without installation thanks to its support for storing settings in the winrar.ini file. WinRAR Portable will be useful both for system administrators and regular users. WinRAR Portable lets you use all the features of the popular archiver without having to install it on every computer. Just recently I found out that there is a perfectly legal way to get WinRAR Portable, install it on a flash drive and use it on any PC.
