on a macintosh under mfs or hfs, the form aiff is stored in the data fork of a file with file type "aiff." this is the same as the formtype of the form aiff.

 INTERCHANGE FILE FORMAT
Then comes an ID that indicates which type of IFF file this is. The main image type is ILBM, audio is either AIFF or 8SVX, animations are ANIM etc. An IFF file will probably have a filename extension related to this file type stored in the file.
The rest of the file is divided into chunks each of which also has a four-byte header and byte count.
The main difference is that, in RIFF files, numbers are little-endian as on Intel processors, whereas in IFF files they are big-endian, as on the Motorola 68000 processors in the Amiga where IFF files were first used.

 Standards and specs: The Interchange File Format (IFF)
While the IFF format might not be actively maintained, or in very widespread use, it offers a lot of insight into generic file format standards and issues that might come up in dealing with them.
The IFF format is a binary file format.
IFF "FTXT" (formatted text) files might not have had all the features of a modern word processor, but the definition is public, and programs supporting the format could generally communicate with each other.

  Interchange File Format - Wikipedia, the free encyclopedia
Interchange File Format (IFF), is a generic file format originally introduced by the Electronic Arts company in 1985 (in cooperation with Commodore-Amiga) in order to ease transfer of data between software products produced by different companies.
Most files with.iff extension are in fact ILBM files, wrongly named so because they are most common IFF files and most assume that they are the only type of IFF files (on many systems that produce IFF files, file extensions are not important).
This is followed by a 32-bit unsigned integer (all integers in IFF files' structure are big-endian) specifying the size of the following data (the chunk content) in bytes.

 (.jpg) JPEG File Interchange Format
JPEG File Interchange Format is a minimal file format which enables JPEG bitstreams to be exchanged between a wide variety of platforms and applications.
Note that JPEG interchange format requires (as does JFIF) that all table specifications used in the encoding process be coded in the bitstream prior to their use.
The syntax of a JFIF file conforms to the syntax for interchange format defined in Annex B of ISO DIS 10918-1.

 Timestream®: Hypermedia Interchange File Format (HIFF)
The Hypermedia Interchange File Format(tm) (HIFF(tm)) standard is a specification for comprehensively describing the form and contents of documents created in and by object-oriented, multimedia or hypermedia application programs.
HIFF files are presently specified to be in readable (and, optionally, editable) text format, limited to the printable ASCII character set to maximize their transportability among environments.
It is a sequential numbering of all objects described in the file, beginning with 1 for the initial \file object, and incremented by 1 for each subsequent object described.

 About Interchange File Format
In a nutshell, IFF helps minimize problems such as new versions of a particular program having trouble reading data files produced by older versions, or needing a new file format everytime a new version needs to store additional information.
Each of these files must start with an ID which indicates that it is indeed an IFF file, followed by an ID that indicates which type of file.
Of course, the ULONG size and file type ID may be different in various files, but nevertheless, a 12 byte header always appears at the beginning of an IFF file.

 Dr. Dobb's | SPIFF: Still Picture Interchange File Format | July 22, 2001
Still picture interchange file format (SPIFF) is a generic bitmap file format defined by the International Telecommunications Union (ITU) and International Standards Organization/International Electrotechnical Commission (ISO/ IEC) for the storage, compression, and interchange of color or grayscale continuous-tone and bitonal image data.
Reasoning that a single file format covering the needs of all applications could not be adequately defined, the Group concluded that the other standards bodies should be left to create their own formats to encapsulate JPEG data.
As Figure 1 illustrates, SPIFF files are composed of four major sections: the header, the information directory, the image data, and an optional section containing indirect data (that is, information too large to fit in the information directory).

 Smart Computing Encyclopedia Entry - Resource Interchange File Format (RIFF)   (Site not responding. Last check: 2007-10-22)
RIFF is much better known, however, as a Microsoft multimedia file format, standing for Resource Interchange File Format.
RIFF files are useful because they can store a wide array of audio, video, and graphical information types.
RIFF files, because they are more a container format, aren’t actually referred to or labeled as a RIFF file, but rather by the type of data they contain.

The appearance of values in the DXF file is not affected by the setting of the UNITS command: coordinates are always represented as decimal (or possibly scientific notation if very large) numbers, and angles are always represented in decimal degrees with zero degrees to the east of origin.
In the case of error loading a DXF file using DXFIN, AutoCAD reports the error with a message indicating the nature of the error and the last line processed in the DXF file before the error was detected.
Unlike ASCII DXF files, which entail a trade-off between size and floating-point accuracy, binary DXF files preserve all of the accuracy in the drawing database.

 RIFF (Resource Interchange File Format)
RIFF (Resource Interchange File Format) is a tagged file structure for multimedia resource files.
Strictly speaking, RIFF is not a file format, but a file structure that defines a class of more specific file formats, some of which are listed here as subtypes.
The RIFF structure is the basis for a few important file formats, but has not been used as the wrapper structure for any file formats developed since the mid 1990s.

There's no need for it, and hopefully, the misguided programmer who conjured it up will be embarrassed into hanging his head in shame when nobody agrees to support his foolishness.
This is not necessarily the same as the number of bytes nor the number of sample points in the Sound Data Chunk (ie, it won't be unless you're dealing with a mono waveform).
It is the responsibility of applications that write data into the lower precedence chunks to make sure that the higher precedence chunks are updated accordingly (ie, so that conflicts tend not to exist).

 Cover Pages: XML Localization Interchange File Format (XLIFF)
As a response to this situation, an initiative to define a standard file format in the localization industry was established.
The purpose of this format is to store localisable data and carry it from one step of the localisation process to the other, while allowing interoperability between tools." From the introduction: "XLIFF is the XML Localisation Interchange File Format designed by a group of software providers, localisation service providers, and localisation tools providers.
The XLIFF data format successfully meets the goal of the separation of localization data and process, providing a focus on automation, stopping the proliferation of internal XML formats, and turning localization into a commodity for all players.
