What Is a ZIP File?
ZIP is the most widely used archive file format that supports lossless data compression. A ZIP file contains one or more files or folders that have been compressed to reduce file size and bundled together for easier storage and transfer. Created by Phil Katz in 1989, the ZIP format has become the universal standard for file compression across all operating systems.
