Footnotes

1. ^ ^a b c d (File extensions)—The file extensions may differ across platforms. The case of these extensions may differ on case-insensitve platforms.
2. ^ ^a b c d (MIME type)—The MIME media types may be conjectural. Very few have been officially registered with the IANA. Compression-only formats should often be denoted by the media type of the uncompressed data, with a content coding indicating the compression format.
3. ^ ^a b c d (Official name)—The official names may be disputed.
4. ^ ^a b c d (Creation platform)—Indicates the platform(s) under which a format can be created.
5. ^ (Restoration platform)—Indicates the platform(s) under which a format can be restored/extracted. Most file formats can be understood by more than one platform.
6. ^ (Restoring with free software)—Indicates whether the format can be restored using an extraction tool that is free software.
