how do you find an image file used in the cameras.dat file

lets say i want to add my own image file for the binocular in cameras.dat

(before anyone gets exited this is purely a "what if" example)

how do i find the image file used for it?

now i dont see anything in the cameras.dat that says binocular.dds file and even though it is easy to find in the menu folder because it is called binocular.dds, you dont always see it named that clearly so i want to know how to locate image files from the dat file.

so if its not easy to find, how can you find what image file something is connected to and follow that back to the image file and its location?



also a second question is:

what if i wanted to leave the existing binocular image alone so it is still used for the german side

but i want to redirect the cameras.dat to use a completely new image i added for US subs instead of the stock image. how would i do that?
