HELLO SARATH
As mentioned correctly by Fayiqa these are the sample files present in the optisystem 14 samples folder.I am also using optisystem 14 and these files are working okay on my system… I really do not think there should be any problem in opening these osd files as far as optisystem 14 is concerned… Give it a try once again.. Hope it works this time…
