Eugene Roshal (; born 1972) is a Russian software engineer best known for developing the RAR file format, the WinRAR archiver, and a file management utility called Far Manager. His contributions have significantly impacted the field of data compression and file management.
In 1993, Roshal developed the RAR (Roshal Archive) file format, designed to offer higher compression ratios compared to existing formats like ZIP. Two years later, in 1995, he released WinRAR, a graphical file archiver utility for Windows that utilizes the RAR format. WinRAR quickly gained popularity due to its efficiency, user-friendly interface, and robust feature set, including support for multiple languages, encryption, and archive repair capabilities.
In 1996, Roshal introduced the FAR (File and Archive Manager) file manager, a text-based file management tool for Windows. FAR is appreciated by developers and power users for its flexibility, plugin support, and efficient handling of files and directories.
While Eugene created the RAR compression algorithm, the copyright is held by his older brother, Alexander Roshal. This arrangement allows Eugene to concentrate on software development without being encumbered by copyright and licensing issues.
