how to disable __FILE__ ?

[Paul McKenzie]

MSVC++ 2008. I can see the full filepaths in my hex editor. I'm compiling a dynamic library (.dll) if that matters.

I thought I just ask to see if there's an easy way to get rid of them,

The easy way is to create your own define, and then do a global search and replace.

#ifdef SHOW_FILE_LINE
    #define MY_FILE_MACRO   __FILE__
    #define MY_LINE_MACRO  __LINE__
#else
    #define MY_FILE_MACRO  
    #define MY_LINE_MACRO  
#endif

And then replace __FILE_ with MY_FILE_MACRO, and __LINE__ with MY_LINE_MACRO.

Typically, I see most people use a #define switch and set them to empty values,

I have never seen this used. Who are these "most people"?

You can't undefine a compiler preprocessor symbol such as __FILE__ and __LINE__ without invoking undefined behaviour. The __FILE__ and __LINE__ macros are not only compiler macros, they are mandated by the ANSI C++ rules to perform as described -- you can't change them.
