Career
Development of RAR and WinRAR
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

FAR File Manager
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.
Ownership and Copyright
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.
