how to get file names vs directory names in c++ (using boost filesystem library)

5.9k views Asked by At

When I use boost::filesystem to get a list of file names in a directory, I receive file names as well as directory names:

#include <string>
#include <iostream>
#include <boost/filesystem.hpp>
using namespace std;
using namespace boost::filesystem;

int main()
{
    path p("D:/AnyFolder");
    for (auto i = directory_iterator(p); i != directory_iterator(); i++)
    {
        cout << i->path().filename().string() << endl;
    }
}

Output is like:

file1.txt
file2.dat
Folder1 //which is a folder

Is there a quick way to distinguish between files and folders? My OS is Windows 8.1, if it matters.

Final code:

#include <string>
#include <iostream>
#include <boost/filesystem.hpp>
using namespace std;
using namespace boost::filesystem;

int main()
{
    path p("D:/AnyFolder");
    for (auto i = directory_iterator(p); i != directory_iterator(); i++)
    {
        if (!is_directory(i->path())) //we eliminate directories in a list
        {
            cout << i->path().filename().string() << endl;
        }
        else
            continue;
    }
}

Output is like:

file1.txt
file2.dat
