WinRAR is a powerful file manager. It can back up your data and reduce the size of email attachments, open and decompress RAR, ZIP, and other files downloaded from the Internet, and create new archives in RAR and ZIP file formats.
WinRAR is a technically superior file compressor. It offers higher compression ratios than other compression tools for PCs, especially on executable files, object libraries, and large text files. It also features solid compression.
RAR was the first compressor to implement 64-bit file handling, allowing it to manage large numbers of files and extremely large file sizes (only limited by the operating system). WinRAR supports files and archives of up to 9,000 Petabytes. The number of archived files is, for all practical purposes, unlimited.
