Fallout: Brotherhood of steel
 

I am trying to backup Fallout and it is too big to fit on a disc.

I have done a search and cannot find any posts about this so can anyone suggest what files to remove to make this fit???

Look throuh the movie files and remove any that are noted to be out of your region, like japanese movies if you are in the US. If this can't be one you may need to downgrade the movies, but most games will fit by removing foreign movies.

Thanks for that, as I am only new to backing up my games how do I tell which files are movie files and which region they belong to and how do I downgrade movie files??? By the way I am in Australia.

In most cases I have seen the movie files were clearly labeled. Somewhere in the tutorials section at xbox-scene are instruction on how to do both. You can look here
