WinRAR is not just as simple as compression

As long as you use a computer, you will definitely get in touch with compressed files! From a professional point of view, compression is actually a program algorithm. With this algorithm, a large file can be compressed as small as a compressed cookie, thus saving a lot of hard disk space. When you need to use this compressed file, The file data can be restored (ie, decompressed) by an algorithm. There are a lot of popular compression/decompression software on the web, the most famous ones are WinZip and WinRAR. Among them, WinRAR not only has most of the features of WinZip, but also provides a RAR compression format with a higher compression ratio than ZIP, so that it will become the mainstream compression/decompression software.

Do you know?

WinRAR is actually just a shell of RAR compression software, making it easier for us to use RAR. In the DOS era, RAR was not the first compression software. At the time, compression tools such as Pkzip and Arj were more popular than RAR. When RAR launched version 2.0 (see Figure 7), people were surprised to find that it actually took the window to work, and also supported mouse operations, especially its compression ratio and compression speed, let users look at it. It is also from this version that RAR came to the fore and gradually became a favorite compression tool.
