Are you sure there is no typo ? I am not able to find information on the .src file extension. It does not seem to exist.
Do you know what is in the file ? Where/how did you get those files ? Maybe you can try renaming the files with a suitable extension. Please also provide the actual name of a file - maybe that will provide a clue. The examples you have provided (if they are actual names) point to picture files, so try changing the extensions to picture formats, e.g. .bmp, .jpeg, etc. or maybe movie files - .mov, .avi, etc.
I cant open any files ending with .src
joe.src / car.src / house.src
