Hello, I have a bunch of old IDX and DAT files created around 1998-2000, there isn't any exe files to view them but there is an old ctreestd.dll confirming my suspicion that they were FairCom C-Tree database format.. But the new C-TreeACE does not contain a program that is able to open them. Does anyone know of any program that is able to do so, and export the data? Or would it be easier for me to write an executable that calls the functions in the DLL, which are the same format as the newer version.

Many thanks, David.
