rizpaq
A portable Windows GUI for the zpaqfranz archiver: file versions like
ZPAQ power without the console.
Rizpaq is a portable archiver for Windows built on zpaqfranz: every run adds a file version — open a folder as it looked on any date, compare two versions, or restore one file as it was six months ago. Identical content is stored once (deduplication): a 50 GB library changing 200 MB a month stays ~51 GB with twelve restore points. It opens, extracts and converts ZIP, 7z and RAR on the spot, and wraps every archive into a PAR2 set that detects and repairs bit rot.
Inside: a catalog and global search across all archives on the computer; backup tasks with silent scheduled runs and integrity checks; compression from "store" (m0) to extreme (m5) with a visual -method constructor; two-way drag & drop; Explorer integration; checksum-verified one-click updates; ten fully native languages.
Portable, no installer: zpaqfranz, 7z and par2 engines are built in. Windows 10/11 x64, MIT license.
