1. ZIP file format is to archive several files into a single file and to minimize its size.
2. ZIP is a fairly simple archive format that compresses every file separately. Compressing files separately allows for individual files to be retrieved without reading through other data.
3. ZIP supports a straightforward password-based symmetric encryption system which is known to be seriously flawed.
4. Some windows ZIP tools also support NTFS file system permissions, and will make an attempt to translate from NTFS permissions to UNIX permissions or vise-versa when extracting files.
