- Description
- StuffIt X Archive (.sitx) is a compressed archive format introduced in 2002 as the successor to the classic StuffIt (.sit) format. It offers stronger compression than the original format and adds encryption, error correction, and self-checking features, while preserving Mac-specific data such as resource forks. It has been widely used on classic Mac OS and macOS for bundling and distributing files.
