The key difference between tut3.cpp and tut4.cpp is - what happens in the directory iteration loop. We changed:

-
- 
cout << " " << *it << '\n';   // *it returns a directory_entry,
-
-

to:

-
- 
path fn = it->path().filename();   // extract the filename from the path
-v.push_back(fn);                   // push into vector for later sorting
-
-

path() - is a directory_entry observer function. - filename() is one of +

filename() is one of several path decomposition functions. It extracts the filename portion ("index.html") from a path ("/home/beman/boost/trunk/index.html"). These decomposition functions are more fully explored in the Path iterators, observers, composition, decomposition and query portion of this tutorial.

-

The above was written as two lines of code for clarity. It could have - been written more concisely as:

-
- 
v.push_back(it->path().filename()); // we only care about the filename
-
