The fd file extension is associated with the DataFlex software.
The fd file contains an association between the real name of a datafile and the internal DataFlex number.
The fd files also contain information about the definition of each column in a DataFlex table.
This is used by the DataFlex compiler to associate file and field references in source code with an internal numbering scheme used within the DataFlex runtime.
The *.fd files are used for internal purposes of DataFlex.
Conversion to other formats is not possible.

LaTeX uses .fd files as part of its New Font Selection Scheme. A file associates a font family and encoding with the font shapes and sizes that LaTeX can select.
Font definition files contain LaTeX declarations, such as definitions for a font family and its available shapes and series. They work with the font files and LaTeX packages installed in a LaTeX distribution.
The format remains in use wherever LaTeX font packages require font definitions, including LaTeX installations on Microsoft Windows.
An .fd file is a plain-text file. On Microsoft Windows, it can be opened and edited with WinEdt or another text editor.
Users normally do not open these files directly. LaTeX reads the appropriate .fd file automatically while processing a document that uses the associated font.
An .fd file is a text-based configuration file rather than a document or a font, so it normally has no useful conversion target.
To use the definitions in another LaTeX setup, copy the file with the related font package or edit its LaTeX declarations manually. Changes should be made only when the corresponding fonts are also available.

LaTeX font definition files contain declarations that tell LaTeX how to select fonts for a particular encoding, family, series and shape. They are used by LaTeX's font selection system when a document requests a font.
These files are usually installed as part of a LaTeX font package rather than created as documents. LaTeX reads them when needed and uses them together with the related font metric and font files. The format remains in use, including in LaTeX installations for Microsoft Windows.
An .fd file is a plain text file, so it can be opened and inspected with any text editor. On Microsoft Windows, a LaTeX installation reads the file automatically when it is needed during document processing.
Use a text editor rather than a word processor if the file must be edited, and preserve its plain-text formatting and LaTeX commands.
An .fd file is not normally converted to another format. It is a text-based configuration file whose declarations are used directly by LaTeX.
If a different font definition is required, the file can be edited or a suitable LaTeX font package can be installed. Compiling a LaTeX document may produce a PDF, but that converts the document, not the .fd file.

The fd file extension is used by STK (Systems Tool Kit), originally developed by Analytical Graphics, Inc. and now developed by Ansys. STK models and analyzes objects and their locations in a three-dimensional environment.
An fd file stores the main data for an STK facility database. The database provides facility information that STK uses when working with facility objects and related analyses.
This is an application data file rather than a document intended for independent use. Its contents are managed by STK, and the file should normally remain with the other files that make up the associated facility database.
Install STK on Microsoft Windows and open or load the associated facility database from within STK's facility database tools. An fd file is not normally opened directly as a standalone document.
Do not edit the file in a text editor or rename it to another format, because STK expects its facility database data in its original form.
An fd file is used as part of an STK facility database, so it is not normally converted with a general file converter.
To transfer facility data, use the database management or export features provided by the relevant version of STK, when available.
