A file is a class of objects you probably perform operations on with your scripting. You could instead use some kind of function instead to change, say, the entries in the disk index used to map sectors but using a class function like "rename" is just so much more understandable from the human point of view. You asked for an example where a class is more suitable than a function. I can think of no better example than the abstract concept of files on a modern operating system. In fact it's so useful you will probably have difficulty coming up with ways to perform the same operations without using an object-oriented strategy.
