: It supports AES-256 encryption for both file data and the file structure itself (header encryption).
: Unlike standard ZIP files, 7z can use a sliding dictionary of up to 4 GB , allowing it to find patterns and redundancies across much larger files. AnImpressiveFeat.7z
: These are the core technologies behind 7z. LZMA (Lempel-Ziv-Markov chain algorithm) is highly regarded for its high compression ratio and relatively fast decompression. : It supports AES-256 encryption for both file
