No bloat.

If you stumble upon a .arc archive from 2012—perhaps a backup of a defunct forum or a game mod pack—FreeArc Portable is the only lightweight way to open it without installing ancient software.

FreeArc Portable is a standalone, open-source file archiver known for offering some of the highest compression ratios in the software world. Unlike standard installation versions, the portable edition runs directly from a USB drive or cloud folder without modifying your system registry or leaving configuration files behind. freearc portable
