What is HatchZip?
HatchZip is a free, open-source archive extractor for Windows, macOS, and Linux. It extracts ZIP, 7z, RAR, and tar files in place, meaning it only requires free disk space for the extracted files, not for both the archive and the files at the same time. This makes it useful for large downloads where storage is limited.
The tool works by reading from the end of the archive and removing completed sections once the data is safely written to disk. It checks available space before starting any extraction and will refuse to run if there is not enough room. If interrupted, it can resume exactly where it left off. Every file is verified with a CRC-32 check during the process.
HatchZip includes both a desktop application and a command line interface. It supports password-protected archives, split volumes, and solid RAR files. The software runs completely offline with no networking code, telemetry, or automatic update checks. It is licensed under MIT or Apache 2.0.
