.zipファイルとは？

ZIP is the most widely used archive format, allowing you to compress one or more files into a single, smaller package. Created by Phil Katz in 1989, ZIP uses lossless compression algorithms (primarily DEFLATE) to reduce file sizes without losing any data. ZIP archives are natively supported by Windows, macOS, and Linux, making them the universal choice for sharing files via email, downloading software bundles, and organizing file collections.
