The ZIP file format is a popular lossless data compression and archival format created by Phil Katz, founder of PKWARE. A ZIP file contains one or more files that have been compressed, to reduce their file size, or stored as-is. A number of compression algorithms are permitted in zip files but in 2008 only DEFLATE is widely used and supported.
Usage [change]
ZIP files generally use the file extensions ".zip" or ".ZIP" and the MIME media type application/zip. Some software uses the ZIP file format as a wrapper for a large number of small items in a specific structure. Generally when this is done a different file extension is used.
