.file extension EXF - Exchangeable Image File Format
File extension EXF description:
Exif (despite being an acronynm it is usually written as "Exif" rather than "EXIF") is a file format developed by the Japan Electronic Industry Development Association (JEIDA) principally for use by digital cameras. The specification uses the JPEG, TIFF and RIFF formats, with the addition of metadata tags.
There are some issues with the Exif format, including:
* If Exif files are read by programs other than the original manufacturer, their maybe metadata (data describing the image) which can not be read, and which becomes corrupt or lost if the file is then re-saved in Exif format.
* The standard defines a markernote tag which manufacturers can use to store any data they wish in. As this tag is proprietary and manufacturer specific, it is difficult, if not impossible to read this information or preserve when re-saving the image.
* Exif is limited to 24 bit color depth.
* Exif has no provision for video.

Photo Studio is also a useful tool for exploring the meta data stored along with your image files. The program supports a wide variety of meta data standards, including EXIF, CIFF, Olympus, JFIF and Photoshop. EXIF data will be of particular interest to digital camera users - it is the format used by most digital cameras to store camera settings along with an image.
The tool also has basic support for some movie formats - AVI and QuickTime/JPEG, as recorded by some older digital cameras. The tool can play back, as well as extract video, audio and stills from these files.
