Zip may refer to any of the following:

ZIP file

1. ZIP is a lossless-compression binary file format developed by Phillip Katz in 1989. It is used by compression utilities such as WinZip or PKZIP.

The ZIP file format is also an archive file format. It can contain multiple files combined and compressed into one file. The resulting ZIP file may later be decompressed to re-create the original files.

The file extension of a ZIP file is .ZIP or .zip. Depending on the types of files archived and compressed, the resulting ZIP file's size may be significantly smaller than the combined size of the original files.


The original MIME (multipurpose Internet mail extensions) specification of the ZIP file format lists "ZIP" in all uppercase letters, but it is not an acronym.
