What is ZIP?
ZIP is a widely used archive file format that supports lossless data compression. A ZIP file contains one or more files that have been compressed to reduce their size, making them easier to store and transmit. The format was created by Phil Katz in 1989 and has become the de facto standard for file compression and archiving across all major operating systems.
File Format: ZIP files use .zip extension and act as containers that can hold multiple files and folders in a compressed format. The format uses various compression algorithms, with DEFLATE being the most common.
Compression: Supports multiple compression methods including DEFLATE (default), LZMA, BZIP2, and PPMD. Can achieve significant size reduction, especially for text-based files and documents with repetitive data.
Structure: ZIP files are structured as a series of "local file headers" followed by compressed data and a "central directory" at the end. This design allows random access to individual files within the archive.
Encryption: Supports password protection using traditional ZIP crypto or more secure AES encryption (AES-256). Encrypted ZIP files require a password to extract contents.
Compatibility: Natively supported by Windows, macOS, Linux, and most mobile operating systems. No additional software required to extract ZIP files on modern systems.
