ZIP files have capability to store multiple files using different compression techniques while at the same time supports storing a file without any compression. In order to render the compressed files, a ZIP archive holds a directory at its end that keeps the entry of the contained files and their location in the archive file. It, thus, plays the role of encoding for encapsulating information necessary to render the compressed files.

The format keeps dual copies of the directory structure to provide greater protection against loss of data. Each file in a ZIP archive is represented as an individual entry where each entry consists of a Local File Header followed by the compressed file data. The Directory at the end of archive holds the references to all these file entries.

ZIP file readers should avoid reading the local file headers and all sort of file listing should be read from the Directory. This Directory is the only source for valid file entries in the archive as files can be appended towards the end of the archive as well. That is why if a reader reads local headers of a ZIP archive from the beginning, it may read invalid deleted entries as well those are not part of the Directory being deleted from archive.

The order of the file entries in the central directory need not coincide with the order of file entries in the archive. Desktop Enhancements. Networking Software. Trending from CNET.
