I've been working on a photoshop project, when i started working it was a Psd file but after a while it saved my further progress as a Psb file. I had been saving constantly and I can see the file but it will not open. I have the current version of photoshop. Any solutions or suggestions?

How big is the file on disk? Could you post a copy of the file for us to troubleshoot?
