File Format ReferencesExtensible Markup LanguageThese Files are all based on the XML language. Each format defines a set of tags that are used to communicate the appropriate data. .GPX XML based GPS DataThese files store GPS related data in an XML based file. .LOC Location GPS DataThese files store GPS related data in an XML based file. .SVG Scalable Vector GraphicsSVG is a XML based language for vector graphics. .XML Extensible Markup LanguageOriginally evolved from SGML and HTML, XML is a tag based hierarchal language used to store and describe text data. .XMP Extensible Metadata PlatformThis is an XML file containing metadata, usually as a sidecar file to an image. XMP data is normally embedded into JPEG, PSD and TIFF files. FAT Based FilesThese files have a header which contains an allocation table (similar to a FAT). The Data is stored into fixed size sectors and linked from the allocation table. .DBThe thumbs.db file is used by windows to store thumbnail images for quick access while browsing. .DOC .VSD .XLSThese Microsoft Office files all use the FAT format to save data .FPX FlashPixFlashPix is a file format used on select digital camera. A version of FlashPix called FlashPix Ready data can also be found embedded into the EXIF information in images such as JPEGs. JPEG Image FormatThe Joint Photography Experts Group developed JPEG as a compression algorithm and the JPEG Image Format (JIF) as its container. It is most commonly used with photographs because they are more forgiving of JPEGs lossy compression. The JPEG format uses markers to define the file. More on the JPEG Image File can be found Here. .JPG .JIF .JPEG JPEG Image FormatThis is the most common file format for pictures. .JPS Stereo JPEG.JPS is a standard JPEG file with a single image created from two stereo images placed side-by-side. The images are stored "cross-eyed", the 3D stereo left image is on the right of the JPEG image and the right image is stored on the left side. The JPEG image is twice the width of the intended 3D image. .MPO Multi-Picture OutputThis is a JPEG based file that is designed to store multiple images. Typically it is used to store the Left and Right images of a 3D Stereo image. It is also occasionally used to store multi-capture panoramas. The MPO file uses a Multi-Picture Format (MPF) APP2 marker to store picture information in a TIFF styled format. .THM

MPEG StreamsMPEG-1 and MPEG-2 formats .MP3 MP3 Audio FileThese are the de-facto standard for compressed audio. .MP3 files can contain two versions of ID3 metadata which can include images for album art. .MP3 also supports APE tags for metadata. http://en.wikipedia.org/wiki/MP3 APE Metadata http://wiki.hydrogenaudio.org/index.php?title=APEv2_specification .MPG MPEG Moviehttp://dvd.sourceforge.net/dvdinfo/pes-hdr.html http://dvd.sourceforge.net/dvdinfo/mpeghdrs.html .MTS .M2TS MPEG-2 Transport StreamThis type of file is composed of a collection of MPEG-2 packets http://en.wikipedia.org/wiki/MPEG_transport_stream Resource Interchange File FormatThe Resource Interchange Format is a generic container format for storing data in chunks. .AIFF Audio Interchange File FormatAIFF is a little-endian alternate version of RIFF developed by Apple. .ANI Animation.AVI Audio Video Interleave.RMI RIFF MIDI.SFL SoundForge.WAV Waveform Audio File FormatAlso known as Audio for Windows, this format is mainly used to record un-compressed audio. .WEBP WebPGoogle created WebP to be a new format for compressed internet graphics to compete with PNG and JPEG. QuickTimeQuickTime was developed by Apple, it is based on Atoms which contain data and other Atoms. A QuickTime file can contain multiple tracks, which can be audio, video or data. It is the basis for the ISO Base Media File Format which is the container for MPEG-4 and 3GP files. .3G2 .3GP 3GPP - Third Generation Partnership ProjectThese files were designed for 3G phones based on MPEG-4 (MP4) file format. .3GP for GSM phone, .3G2 for CDMA phones. .AAX Audible Enhanced AudiobookAudible.com's QuickTime derived format with Digital Rights Management (DRM). .JP2 JPEG 2000This type of image file combines a ISO Base Media File with a JPEG marker based codestream. JPEG2000 offers a newer method of compression, but is not compatible with standard JPEF (.JPG) files. .M4A MPEG-4 Audio FileThis is a .MP4 file that just contains audio tracks. .M4P MPEG-4 Protected FileThis is an extension of the .MP4 file which incorporates Apple's Digital Rights Management and also supports AC3 (Dolby Digital). .M4V MPEG-4 Video FileThis is a .MP4 file that contains a video. .MOV .QT QuickTimeThe original QuickTime format. QuickTime is also the name of Apple's QuickTime File Format player software. http://developer.apple.com QuickTime Reference .MP4 MPEG-4 FileThe .MP4 file is an ISO Base Media file used to store MPEG-4 compressed video and audio. http://www.mp4ra.org/specs.html http://atomicparsley.sourceforge.net/mpeg-4files.html Tagged Image File FormatTIFF is a very extensible image format created by Adobe. It supports various image and compression formats as well as multiple images and data within one file using its Image File Directory (IFD) structure. .CR2 Canon Raw File.CR2 is the RAW file used in Canon dSLR cameras. .DNG Digital NegativeThis is a format created by Adobe to be used as a RAW image format. .EXIF - Exchangeable Image File Format.EXIF files are typically used as sidecar which store metadata for an image. EXIF data can also be stored in JPEG, TIFF, WAV and other file formats. .NEF - Nikon Electronic FormatThis is Nikons RAW file format. .TIF Tagged Image File FormatTIFFs structure is based on groups of tags that link to various types of data. Adobe provides the standard listing of tag numbers and the tags themselves describe the data that accompanies them. http://en.wikipedia.org/wiki/Tag_Image_File_Format_/_Electronic_Photography ZIP Compressed FilesThese files are based on the PK-Zip format. Originally designed to store compressed files, they can also store compressed data. It uses a directory structure where the directory contains offsets to each file. .ZIP Compressed FilesThese are the original PK-Zip format. They support file compression, as well as backup across multiple diskettes. .XLSX .XPS .DOCX .PPTX Compressed Microsoft Office FilesThese files store XML and other data in a ZIP format. .ODP .ODT .ODS .ODB .ODG .ODF - OpenDocument FilesOther Formats.BMP - Bitmap FileThese files store raster images, typically uncompressed. Several different levels of color depth are available from monochrome to 32-bpp. .CT .SCT Scitex Continuous ToneContinuous Tone files used on non-binary digital printing equipment. .EMF Enhanced MetaFile.EPS Encapsulated PostScript.GIF Graphics Interchange FormatThese files use lossless compression and limited color palette to provide small file sizes suitable for web graphics. The GIF format also supports animations and transparency. .ICO .CUR Icon and Cursor BitmapsThis bitmap formats are used to store icons and cursors used in Microsoft Windows. This format can contain multiple versions of the same image. http://en.wikipedia.org/wiki/ICO_(file_format) .ICC International Color ConsortiumThis type of file stores color conversion information.
