WinRAR is one of the most popular compression and extraction programs around. There are several reasons for that but we have to point out its compatibility with a wide range of formats, how easy it is to use and the fact that we can still use it for free even after its trial period is over.
The portable version of WinRAR
And many users have resorted to WinRAR Portable (Unplugged), the portable version of this software. Mainly because it allows us to deal with compressed files on any PC even if we haven't got permission to install software. We only have to run it from a USB stick and that's it. The same goes if we want to send several files as an email attachment from a computer with restricted use, at school or work, for instance.
It comes along with the majority of functions that we can find in the full version of WinRAR:
- Compression of files in RAR and ZIP format.
- Extraction of files in RAR, ZIP, ARJ, TAR, CAB, JAR, ISO, 7Z, and BZ2 format, amongst others.
- Protection of compressed files by means of encrypted passwords using the 256-bit AES protocol and digital signatures.
- Creation of auto-extractable files and multi-volume partitions.
All in all, it's a must-have tool that can't be missing on your USB stick together with all your other emergency programs.
