# Translate Format Information

Format information can include file attributes in the following categories:

- Major format
- File class
- Minor format
- Major version
- Minor version

Not all categories are required. Many formats only include major format and file class, or major format only.

The format information has the following structure:

    MajorFormat.FileClass.MinorFormat.MajorVersion.MinorVersion

For example:

    81.2.0.9.0

Each number in the format information represents a file attribute. The entry `81.2.0.9.0` represents a Lotus 1-2-3 Spreadsheet file version 9.0, where

`81`= Lotus 1-2-3 Spreadsheet (major format)

`2` = Spreadsheet (file class)

`0` = not defined (minor format)

`9` = 9 (major version)

`0` = 0 (minor version)

This example applies to the `formats.ini` file. When extracting format information using the `fpDocInfoFile()` or `fpDocInfoStream()` functions, the same format is represented as `294.2.9.0`.

NOTE: The format values returned from `fpDocInfoFile()` or `fpDocInfoStream()` differ from those in `formats.ini` because the former defines a unique ID for each major format, while the latter uses a major version, minor version, and minor format to distinguish between formats.
