Now I am learning to develop screens in cx designer, actually in this beginning stage I got some confidence  in creating screens, actually I can’t accept that I had lost that file,   Anyway ,I understood now ,I had lost that file. After posting this message , I am doing further works by opening a new project, I am trying to know ,how to retrieve the data in such files, in future, If the same problem happen in the upcoming projects. If there is any problem, there will be solution too.in 90 % cases. If we think there is a chance of problem, we should find the solution before that problem occur…..    

thanks for your reply.yes i am planning to change system.but at the same time i am trying to retrieve the data in that corrupted file.

I was working On Cx designer to to create NS series HMI. When I gave command to save the screens, within that 5 seconds of saving time              Due to sudden power shut down my PC also shut down at the time of saving the File . After that I tried to open that file after power came, it is showing as “Project Failed to read “new screens”. Please, I need help to open that file.
