The gdt file extension is associated with Genbox Family History, genealogy software from Thoughtful Creations.
A gdt file uses Genbox Family History's default dictionary format. It stores words and phrases that the program uses as dictionary data rather than as a family-history document.

The GDT format has been used for game information in the Call of Duty gaming series. The exact data depends on the particular game release and installation.
It is not clear whether this file type was also used in some of the sequels. A GDT file should be considered specific to the game installation from which it came, rather than a general-purpose information format.
GDT files are intended to support the Windows game and are not normally opened as standalone documents. The format is not a commonly supported interchange format outside the relevant Call of Duty software.
There is no known general-purpose viewer for this type of .gdt file. The associated Call of Duty game for Microsoft Windows normally reads the file from its expected game-data location.
No standard converter is available for Call of Duty .gdt files. They contain game-specific data rather than information intended for export to another format.

SmartWare uses the GDT format as one of its default file types for text graphs. These files contain text graph data created in the program.
This is an old, program-specific format. It is not commonly supported by modern software, so the original SmartWare program may be required to access the contents.
These files can apparently only be opened in the original SmartWare program for Microsoft Windows. Other applications may not recognize them correctly.
We do not know of any dedicated converter for SmartWare text graph files. If the file opens in SmartWare, use any export or save options provided by that program to create a more widely usable copy.
