# File Formats and Document Readers

The configuration file `formats.ini` contains a section named `[Formats]`. Each line in this section matches a file format with the reader to use to parse the format. For most file formats there is only one suitable reader, but for some formats you can choose a reader to use.

Each file format has the following structure, where the parts following `MajorFormat` are optional:

    MajorFormat.FileClass.MinorFormat.MajorVersion.MinorVersion

The reader to use for parsing each format is specified as an abbreviation of the reader's library name. Adding "`sr`" to the end of an abbreviation creates the name of the reader. For example, the following line specifies that an Adobe PDF file (format 230) should be parsed by the reader `pdfsr`:

    230=pdf

NOTE: The `formats.ini` file applies to all formats except graphics. Detection of graphics formats is handled by an internal module named KeyView Picture Interchange Format (KPIF).
