# Key to Supported Formats Table

The supported formats table includes the following information:

Column | Description
--- | ---
Format Name | The format name that is returned by file format detection.
Number | The format number that is returned by file format detection.
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. File Content Extraction 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.
Encrypted | Many file formats offer encryption to protect file content. This column specifies whether File Content Extraction can detect encrypted forms of the file format. If there is a check mark in this column, the encrypted property might be set in the results from format detection.
Metadata | Specifies whether File Content Extraction can extract metadata from the file format. File Content Extraction can extract metadata in several different ways: The reader associated with a file format can extract metadata. Readers that extract metadata have a "Y" in the "Metadata" column of the readers table, but this isn't the only way that File Content Extraction extracts metadata. Using a central metadata library that handles many file formats. Using libraries that target metadata storage methods common to multiple formats (for example, XMP, OLE, or Exif).
File Class | The file class.
