RAR Extractor

Purpose & User Intent: This tool enables reliable extraction of RAR archives on Windows 10 in automated or manual workflows. It serves IT teams, developers, and data engineers who process archived distributions, datasets, or backups and require deterministic results with clear error reporting. Core Logic & Features: The tool accepts a RAR file (single or multipart) and an optional password, extracting to a specified output directory. It verifies archive integrity, preserves file paths, and supports password handling. Advanced options include listing contents without extraction, selective extraction by pattern, and detailed logs for auditing. Inputs & Outputs: Inputs include input_path, output_dir, password, extract_all, and file_pattern. Outputs include extracted_files with paths and sizes, total_size in bytes, success flag, optional error_code, and warnings. Algorithms & Calculations: Extraction follows standard RAR rules; segments are processed in order, password verification occurs before extraction, and total_size is the sum of extracted files. Error handling maps to codes such as WrongPassword, CorruptArchive, and IOErrors. Edge Cases: Missing inputs or unreadable files produce errors; wrong passwords yield WrongPassword; corrupted or unsupported archives yield relevant error codes; very large archives may require chunked processing with progress logging. Localization: Path handling uses Windows conventions; sizes are in bytes; UTF-8 encoding assumed; supports Windows 10 regional settings. Assumptions & Exclusions: Assumes read access to input and write access to output; does not modify the archive; not a GUI tool; no network-based extraction. Use cases include batch automation, server maintenance tasks, and backup restoration pipelines.
