Sometimes files are too big to be downloaded and shared in their normal format, or you may want to send multiple files all at once. A compression and decompression utility allows you to compress files with a certain file extension called a WinRAR.
The RAR file extension stands for "Roshal Archive," as it was named after Eugene Roshal who developed this proprietary technology format. This file is similar to the Zip compression format but has a higher compression level than what can be found with Zip compression files. In fact, 7-Zip utilizes RAR algorithms for the compression of files.
What makes RAR files so popular is the variety of features it gives. It allows you to compress a single file or to place multiple files into a single archive to keep the files organized to minimize the amount of computer memory and space needed. You can also split up large RAR files into smaller sub files that you can later rejoin together at your convenience, enabling you to decompress the large archive when needed.
