I think the new file.c function API could be better:
bool File_ChangeFileExtension(const char *Filename_old, const char 
*Extension_old , char *Filename_new , const char *Extension_new)

IMHO that function should either get max size for given new filename
pointer as arg, or it should allocate and return the new filename.
Not rely on given string being of certain lenght.

(Already existing File_MakeAbsolute*() and File_SplitPath() are similarly
ugly, but I don't think that's a good reason to add more of such things.
:-))
