: It uses AES-256 encryption to protect both the file content and the archive headers (file names), making it difficult for unauthorized users to even see what is inside without a password.
The 7z format, developed by Igor Pavlov, offers several advanced features:
: It can handle archives up to 16 exbibytes (approximately 16 billion GB).
: This feature treats multiple files as a single data stream to find similarities and further reduce size.
: Utilizing the LZMA and LZMA2 algorithms, it typically achieves 30–70% better compression than the standard ZIP format.
: Supports file names in various languages using Unicode.
