That would be nearly all files - hidden files would stay hidden. If you 
want to see ALL files, add the -A option.

You are not allowed to write to "/files.txt".

No, it doesn't because sudo then only works for the ls command, not for 
the output redirection. Try

sudo ls -sSR / >~/files.txt

which will give you a list of all files but place the output in your 
home directory.

There is no big difference between sudo and gksudo in this case because, 
like sudo, it operates on the ls command not on the output redirection.
