Lost all my files

I was in the sns-hdr software when I had the batch process up but not running, my wife came into to talk to me and suddenly all the files in a program, all the files, were gone. A screen came up next to the batch process and it deleted or saved, not sure, everything. Is there anything that I could have touched, is there anything that would delete files?
80 some files that I have no photos for, all real estate photos. Some of which I really need now.
Any help would be greatly appreciated.
