Format used by Web publishers to offer frequently updated information as "channels;" distributed from a Web server to computers with compatible Web browser software installed.

File create in the Common Data Format (CDF), a format used for storing scalar and multidimensional data in a manner independent of the target platform and discipline; used as a scientific data storage and interchange format by various researchers and organizations and often by those in government.

Common Data Format files can be manipulated using the CDF software toolkit provided by the Space Physics Data Facility (SPDF), a part of the Goddard Space Flight Center (GSFC). The software is cross-platform. The Common Data Format is supported with interfaces to programming languages such as C, Fortran, C#, Perl, Java. It is also supported by commercial software packages such as MathWorks MATLAB, ITT Visual Information Solutions' Interactive Display Language (IDL), and Weisang FlexPro. The CDF format has been adopted as a standard format by organizations such as the International Solar-Terrestrial Physics (ISTP) project and the Central Data Handling Facilities (CDHF) project, a scientific data processing entity. NOTE: The CDF format differs from the NetCDF format, which is based on CDF but uses slightly different conventions. Sometimes NetCDF files use the ".cdf" extension, but the format is incompatible.

Interactive document created in the Computable Document Format (CDF), a document standard developed by Wolfram Research; may contain interactive graphs and other visual materials in addition to static text and page formatting; can load visualization data on-demand from within the document file.

CDF documents can be used for various purposes, including business presentations, journal articles, and e-learning materials such as textbooks and tutorials. The format is used by teachers, scientists, publishers, and others. CDF files can be opened using the Wolfram CDF Player, which is a standalone application and a Web browser plug-in provided freely by Wolfram Research. The player supports Mac, Windows, Linux, and mobile platforms.

XML-based data format designed for storing and sharing abstract Enterprise Content Management (ECM) content and metadata; can be used to exchange content across repositories and organizations.

The CDF format was originally defined as part of the Content Transformation Services (CTS) framework by the Enterprise Content Management Group (ECMG).

File created by the CryENGINE SDK, a program suite used for building games for PC and console platforms; saves a reference to the character file (.CHR or .CGF) as well as attachments; used in the process of constructing virtual characters for the target game.

Data file created in NetCDF's Common Data Form format, which is based on the standard Common Data Format (CDF) but differs in several ways and therefore is not compatible; used for storing scientific data in a manner independent of the platform and discipline for which it is used; more commonly uses the .NC file extension.

NOTE: NcView only runs on Windows under Cygwin and if you compile from source manually.

Accounting data file created by Nominal Small Business Accounting, an application used to track company finances; contains accounts, purchase and sale items, exchange terms, payment methods, tax codes, and employee payroll information for a company.

CDF files can be used for storing all accounting information for a small-sized business.
