Really sorry to be a pest, thanks alot for all the replies, I'm making 
progress.

what i am trying now is:

path test("Test2")
string randomString="Random";
directory_iterator  dir_itr(test);
rename(*dir_itr, randomString);

It compiles fine but i get a runtime error, I've used exception handling and 
i get the following message: "Assertion failed: m_imp.get(), file 
c:\boost2\libs\filesystem\build\../src/operations_posix_windows.cpp, line 
317"
