WinRAR is a Windows-only file archiver utility developed by Eugene Roshal for creating and viewing archives in ZIP or RAR file formats. WinRAR can also unpack a variety of archive file formats including ARJ, ACE, CAB, BZIP2, GZ, ISO, JAR, TAR, LHA, UUE, XZ, Z, ZIPX, among other formats. WinRAR was initially released in 1995 but has undergone a lot of transformation through regular updates to make it one of the most popular apps in Windows. WinRAR can be used to test the integrity of the user’s archives by embedding BLAKE2 checksums or CRC32 for every file in every archive. WinRAR can also be used to back up large amounts of data, reduce the sizes of email attachments, decompress ZIP and RAR files, and create new archives in ZIP and RAR format. With better compression, low price, and an easy-to-use user interface, WinRAR is definitely a must-have app on your PC. If you are unsure of buying the app, you can try the free trial o offer after which you can purchase the full version if satisfied with its performance. WinRAR is available in many foreign languages so that everyone can use it.
