# Extract Format Information

To extract format information from a document, use the VAPIMWP_INIT_GETDOCFORMAT parameter of the `VAPIM_INIT` message. This parameter gets format information (such as the file class, format, and version), and populates the `ADDOCINFO` structure. This structure, which is defined in the header file `adinfo.h`, specifies the formats that KeyView can detect. If required, this format information can then be reported to the developer's application.

For information on how to translate the extracted format information, see Translate Format Information.
