## What it is
MultiPar is a Windows Parchive (PAR2) tool for creating recovery files, verifying file integrity, and repairing damaged or missing files. It includes a GUI, command-line clients, and supports checksum formats like SFV, MD5, and FLAC fingerprints, with optional GPU acceleration.

## Use cases
- create par2 recovery files for backups
- verify file integrity with sfv or md5 checksums
- repair corrupted or missing files from par2 archives
- find misnamed or moved files during verification
- protect downloads against data corruption

## When to choose
- you need PAR2-based error correction and file repair on Windows
- you want a GUI plus command-line clients for parity files
- you need GPU-accelerated recovery computation

## When to avoid
- you need a cross-platform or Linux-native par2 tool
- you require an OSI-approved open-source license for redistribution
- you need non-Windows GUI integration

## Facets
- artifact type: application
