Understanding ZIP and 7Z file formats
ZIP is a widely-used archive file format that supports lossless data compression. It can contain one or more files or directories that may have been compressed. ZIP files are commonly used for reducing the size of files and for combining multiple files into a single archive.
7Z is another archive file format that also supports lossless data compression. It is known for its high compression ratio and is used by the 7-Zip software. The 7Z format can include strong AES-256 encryption, and it supports large file sizes and various compression methods.
