| What it does | Why it’s useful |
|--------------|-----------------|
| Detects a set of multipart RAR files (*.part01.rar, *.part02.rar, …) in a directory | No need to manually list every part. |
| Validates that all required parts are present (by checking sequence and file size) | Prevents broken extractions. |
| Merges the parts virtually (no need to create a temporary concatenated file) using the rarfile library, which streams the data directly from the individual parts. | Saves disk space and speeds up the process. |
| Extracts the archive to a target folder, preserving directory structure and file timestamps. | One‑click extraction for the end‑user. |
| Logs progress and errors to both console and a log file (rar_extractor.log). | Easy troubleshooting. |
| Cross‑platform – works on Windows, macOS, and Linux (requires unrar/rar command‑line tool installed). | Portable for any environment you ship the tool to. |
