Lost coins on my computer

Hi anyone, I downloaded some litecoin a few years ago before I had my wallet i believe because my wallet is empty. Is there a file name I can look for that could help indentify where my coins went on my computer ?

standard location is C:\Users(currentuser)\AppData\Roaming\Litecoin\wallet.dat

Yes but is it possible the file is outside of my wallet ? If so it would the file would have an original name?

I bought from Mt gox is there a file name or word I can search for that might indicate a file sent from my gox?
