What Is a ZIP File?

ZIP is the most popular archive format, created in 1989 by Phil Katz. A ZIP file compresses one or more files into a single container, reducing total file size and making it easier to share. ZIP supports:\n- Lossless compression (DEFLATE algorithm)\n- Password protection (AES-256 encryption)\n- File and folder hierarchy\n- Split archives for large files
