How to recover ANSYS file if the wbpj file is missing
 

I was trying to review previous co-worker's CFD and FSI simulation files. Usually one simulation has a ANSYS wbpj file and one folder with the same name containing all the data for this simulation. Somehow the ANSYS wbpj file is missing. Only the data folder of the simulation is left. Is there anyway to recover those data? Thanks.
