Thread: How to display all files, subfiles and directories

I know about FindFirstFile/FindNextFile, so how can i display along the path, for example, C:\Program Files\, all folders and all files enclosed within them, in general, all directories and files along this path. Using only WinAPI + FindFirstFile/FindNextFile, without Boost/Filesystem/dirent.h and etc. Looks like a recursion output with dirent.h, such as:

Code:

#include <stdio.h>
#include <string.h>
#include <dirent.h>
#include "iostream"
#include "string"
#include <windows.h>
#include <fstream>

using namespace std;
void listFilesRecursively(char *path);
int main()
{
  setlocale(LC_ALL , "Russian");
    char path[100];
    printf("Enter path to list files: ");
    scanf("%s", path);
    listFilesRecursively(path);
    return 0;
}
void listFilesRecursively(char *basePath)
{
     WIN32_FILE_ATTRIBUTE_DATA Info;
     char path[1000];
     struct dirent *dp;
     DIR *dir = opendir(basePath);
    if (!dir)
        return;
    while ((dp = readdir(dir)) != NULL)
    {
        if (strcmp(dp->d_name, ".") != 0 && strcmp(dp->d_name, "..") != 0)
        {
            printf("%s\n", dp->d_name);

            strcpy(path, basePath);
            strcat(path, "/");
            strcat(path, dp->d_name);

            string path_s = (const char*) path;
            GetFileAttributesEx(path_s.c_str(), GetFileExInfoStandard, &Info);
            cout<<Info.nFileSizeLow<<endl;
            listFilesRecursively(path);
        }
    }

    closedir(dir);
}

But how to do this using only WinAPI?

I tried like this:

Code:

#include <Windows.h>
#include <iostream>
#include <string>
#include <vector>    

void FindFile(const std::wstring &directory)
{
    std::wstring tmp = directory + L"\\*";
    WIN32_FIND_DATAW file;
    HANDLE search_handle = FindFirstFileW(tmp.c_str(), &file);
    if (search_handle != INVALID_HANDLE_VALUE)
    {
        std::vector<std::wstring> directories;

        do
        {
            if (file.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
            {
                if ((!lstrcmpW(file.cFileName, L".")) || (!lstrcmpW(file.cFileName, L"..")))
                    continue;
            }

            tmp = directory + L"\\" + std::wstring(file.cFileName);
            std::wcout << tmp << std::endl;

            if (file.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
                directories.push_back(tmp);
        }
        while (FindNextFileW(search_handle, &file));

        FindClose(search_handle);

        for(std::vector<std::wstring>::iterator iter = directories.begin(), end = directories.end(); iter != end; ++iter)
            FindFile(*iter);
    }
}

int main()
{
    FindFile(L"C:");
    return 0;
}

But it only displays if the path is in the form of "C:" and does not display subfolders with files.

That was already suggested in the link pointed out by Salem.

By the way this topic should really be in the Windows forum, since using the Windows api is a requirement.
