# Key to Supported Formats Table

The supported formats table includes the following information:

Column | Description
--- | ---
Format Name | The format name that is returned by KeyView format detection. In the C API, these values are defined in the `ENdocFmt` enumeration in `adDocFmt.h`. In the .NET API these values are defined in the `Autonomy.API.Filter.DocFormat` enumeration. In the Java API these values are defined in the `com.verity.api.DocFormat` enumeration. In the C++ API these values are defined in `keyview::Format`, used in `DetectionInfo` which is returned by `Session::detect()`.
Number | The format number that is returned by KeyView format detection. This is the value associated with the Format Name in the relevant enumeration.
Category | This value is used in the KeyView configuration file `formats.ini` to specify the reader to use to filter, export, or view the format. Several formats might have the same category value.
Description | A short description of the file format.
MIME Type | The MIME type (if any).
Extension | A list of common file extensions for the file format. NOTE: This is not a complete list of file extensions. KeyView does not distinguish between file types based on their extension. Instead, it detects the file format based on the file content. This is more reliable because content cannot always be predicted from the file extension, and because some file extensions are associated with multiple formats.
File Class | The KeyView file class. In the C API, these values are defined in the `ENdocClass` enumeration in `adinfo.h`. In the .NET API these values are defined in the `Autonomy.API.Filter.DocClass` enumeration. In the Java API these values are defined in the `com.verity.api.DocClass` enumeration. In the C++ API these values are defined in `keyview::Category`, used in `DetectionInfo` which is returned by `Session::detect()`.
