WinRAR is a well-known file compression utility that can handle all common types of compression files such as Zip, Rar and more, even ISO files. In addition to its obvious advantages in terms of file size reduction, compression, etc., it includes the possibility of using file parity through which you can avoid data loss. This error detection method is generally used in RAID hard disk drives, but can also be implemented in simple programs like WinRAR.
If you have not already downloaded WINRAR, you must do so now. When done, open the folder containing the files you want to protect. Choose the files, right-click on them and choose Add to Archive. You will be taken to the file compression window.
