Disinfectant was an older, popular antivirus program for Apple Macintosh computers. The .d2ct file belongs to the program's supporting data and was used as part of its operation.
The format is obsolete because Disinfectant is no longer maintained and classic Macintosh software is not generally compatible with current macOS. The file has no known modern standalone use.
Open a .d2ct file with the version of Disinfectant that created or used it, on a compatible classic Macintosh system. It is not normally intended to be opened as a standalone document.
Current macOS may not run the classic software required to use this file.
There is no practical standard conversion for a .d2ct file. It is an obsolete supporting file for Disinfectant, not a user document or an interchange format.
