WinRar is such a handy and important software for all PC users. I think almost all the laptop or PC users know about it properly and in fact all of them perhaps used it. This software is a great tool to compress or unzip data files. I have both PC and mobile version installed on my laptop and mobile.
This software is very fast and can expand a compressed or zip files in lightning speed. It also saves data and memory space by backing up data and compressing large files. This software produces files with .rar extension which is recognized by this software in no time.
It has both paid and free version available. To use the paid version, one needs to purchase a license from its official website. But I think its free version is more than enough to do all the necessary jobs. This software is must for my laptop.
