What is an .CDF file?

.CDF is Computable Document Format File

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.

File Type 3 Common Data Format
Developer by: GSFC Category: Data Files

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.

File Type 5 NetCDF Format File
Developer by: NetCDF Category: Data Files

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.

File Type 7 Channel Definition Format
Category: Web Files

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 Type 8 Content Definition File
Developer by: ECMG Category: Data Files Format: XML

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).

How to solve problems with CDF files

  • Associate the CDF file extension with the correct application. On :
    Windows: Right click on any CDF file and then click "Open with" > "Choose another app". Now select another program and check the box "Always use this app to open *.CDF files". Mac: Right click (or Ctrl-click) the CDF file, then click "Open with" > "Other...". Then choose another program and check the "Always Open With" box. Linux: Right click on the file, and select "Open with" and choose another program. iPhone: Tap the file. If you do not see an app to open the file, then tap Share "Share" and choose an app. Alternatively, save the file. Then open the Files app Files app. There long-press on the file, then release your finger. You will see a black menu bar. Then tap "Share" and select an app. Android: Tap the Settings icon on your smartphone, then tap on the Apps section. There tap the Options icon in the top right-hand corner of the screen to change the default apps.
  • Update your software that should actually open .CDF is Computable Document Format File. Because only the current version supports the latest CDF file format. Search, therefore, e.g. on the Wolfram Research manufacturer website after an available .CDF is Computable Document Format File update.
  • To make sure that your CDF file is not corrupted or virus-infected, get the file again and scan it with antivirus software.
