What ZIP and 7Z files are
ZIP
ZIP is the most widely used archive format for compressing and bundling multiple files into a single container. It supports lossless compression and is natively supported by all major operating systems.
7Z
7Z is a high-compression archive format created by the 7-Zip project. It uses the LZMA and LZMA2 algorithms to achieve significantly better compression ratios than ZIP or RAR.
