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 .

Archivers already exist. PKZIP is the king. ARC is the old guard. But Roshal sees inefficiencies. ZIP’s recovery record is weak. Splitting archives across floppy disks is a headache. And the compression ratio? Acceptable, but not optimal. rarlab

This is the story of how two engineers from a small town built an accidental empire on shareware, stubbornness, and one of the most efficient compression algorithms ever written. The year is 1993. The internet is still a dial-up screech. Hard drives are measured in megabytes. In Chelyabinsk, Russia—a city better known for tanks and heavy industry—a software engineer named Eugene Roshal begins writing a file archiver. Roshal does something radical: he designs a new

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. A true original

The result? Estimates suggest that have used WinRAR. Fewer than 5% have paid for it. And Rarlab is perfectly fine with that.

In an industry of surveillance, subscription fees, and forced updates, Rarlab offers a radical alternative: a piece of software that asks nicely, works forever, and never spies on you. It is shareware as it was meant to be—not as a trick, but as an honor system. One day, Windows might die. Linux might fracture. The cloud might absorb all local storage. But the .RAR format will remain—because archives are the fossils of the digital age. Every CD backup, every Usenet post from 2003, every recovered hard drive from a dead relative—they all contain .RAR files.
