Which file format is associated with the WinRAR compression program?

The RAR file format is specifically associated with the WinRAR compression program. RAR, which stands for Roshal Archive, is a proprietary archive file format that can contain one or multiple files in a compressed form. WinRAR is the software developed by Eugene Roshal, which is designed to create and manage RAR files. It offers features such as compression, encryption, and the ability to split files into volumes.

In contrast, ZIP is a different file format that is widely used for file compression and is supported by many different programs, not just WinRAR. ISO is a file format typically used for disk images, which contain all the data from a physical disc. TAR is a file format used mainly on Unix and Linux systems for archiving files, often used in conjunction with compression algorithms. Each of these formats serves distinct purposes and is not limited to the functionalities provided by WinRAR in handling RAR files.
