2.) Look at the API for BufferedWriter.

And define "not the same".
What are you going to use as criteria?
Names only? Sizes too? Or the actual content (and if that, how strict are you going to be? If they're 2 text files that differ only in whitespace, do you consider them the same or not?)?
Get your requirements straight before you even start thinking about putting something together.

I've already told you: File has all of the methods you need. The length() method returns the length of the file in bytes. If the file is a directory, you will need to recursively sum up the length of the files in the that directory, which is obtained with the list() method.
If you had taken the time to look at the APIs that I suggested this should have been fairly straightforward.

Java does not have a native copy method. You must write your own short method for this using the IO classes. There are many implementations of copy available on the internet.

Read the API for FileChannel. The source and destination directory does not make any difference whatsoever, as you are always dealing with two file (or file channel) objects. Where they are makes no difference (to a point). Stop focusing on this system and/or procedural type stuff.
