Roshal does something radical: he designs a new compression algorithm from scratch. Not a tweak. Not a fork. A true original. He calls it — Roshal ARchive .

By allowing anyone (including competitors) to include UnRAR in their software, Rarlab made .RAR a universal format. Every competing archiver—7-Zip, PeaZip, even macOS’s The Unarchiver—can extract RAR files. But only WinRAR can create them (outside of third-party reverse-engineered tools, which are legally shaky).

Memes: “I’ve been using WinRAR for 15 years. Should I pay?” Forums: “Does anyone actually buy WinRAR?” And the legendary tweet from a developer claiming their company had a 12,000-day trial period on a server. rarlab

In many countries—especially Germany, Russia, and Brazil—the WinRAR nag screen has transcended software and become a cultural artifact. Roshal does something radical: he designs a new

If you have ever downloaded a file from the internet, you have touched Rarlab’s DNA. You might not know its founders. You might not know its office address. But you know the three letters it gave the world: .

They tell their colleagues: “Just click ‘Close’ – it still works.” That word of mouth, spanning three decades, has made WinRAR one of the most recognized software brands on Earth without a single Super Bowl ad or billboard. A true original

The brothers Roshal are not tech celebrities. There are no TED talks. No “How We Built Rarlab” LinkedIn essays. Eugene reportedly still writes code. Alexander manages the business. They employ a handful of people. No layoffs. No drama.
