Please forgive my silly questiion.

I did first time to dispatch games/doom, and got

Game mode indeterminate.
                     Public DOOM - v1.10                           
V_Init: allocate screens.
M_LoadDefaults: Load system defaults.
 default file: 
Z_Init: Init zone memory allocation daemon. 
W_Init: Init WADfiles.
Error: W_InitFiles: no files found

What is Wadfiles, and can i get it free?
I just want to try the game to know it's suitable to me.
