如何使用C ++程序在目录中找到子文件夹? [英] how to find the sub folders in directory using c++ program?

问题描述

我想找到桌面上存在的文件夹.

我创建了此编码来获取文件夹.

I want to find the Folders present in the desktop.

I created this coding to get the folders.

#include "stdafx.h"
#include <windows.h>
#include <string>
#include <iostream.h>
#include <vector>
using namespace std;
int num_dirs(const char* path);
int main(int argc, char *argv[])
{
    WIN32_FIND_DATA FindFileData;
    HANDLE hFind;
    string sPath;
    vector<string> MyVect;
    sPath.assign("C:\\Documents and Settings\\yugesh\\Desktop\\*");
    hFind = FindFirstFile(sPath.data(), &FindFileData);
    do
    {
        if(FindFileData.dwFileAttributes == 16)
        {
            MyVect.push_back(FindFileData.cFileName);
        }
    }while (FindNextFile(hFind, &FindFileData));
    FindClose(hFind);
    for(int i =0; i<MyVect.size(); i++)

        cout<<MyVect.at(i).data()<<endl;

    return 0;

}

现在，如何查找文件夹的大小?
FindFileData.nFileSizeLow()未显示.它始终为文件夹提供零值.

还有如何在我找到的那些文件夹中找到子文件夹?

请帮助我..

Now, How to find the size of the folder?
FindFileData.nFileSizeLow() is not displaying.. It always gives the value zero for folders.

Also how to find the sub folders in those folder i found?

Please help me..

推荐答案

您必须遍历子文件和子文件夹的大小以找到文件夹的大小，而不是文件夹本身的属性

并且要找到子文件夹，您必须在其中开始新的搜索...

对于递归解决方案来说，这是一个完美的问题-实际上，任何其他解决方案都将更加困难

you have to iterate through the size of the child file and child folders to find the size of a folder, it''s not an attribute of the folder itself

And to find the child folders you have to start a new search inside it ...

it''s a perfect problem for a recursive solution - in fact, any other solution would be considerably more difficult

我是这样自己完成的..
利用它..


#include"stdafx.h"
#include< windows.h>
#include< Shlobj.h>
#include< iostream.h>
#include< stdlib.h>
#include< string>
#include< vector>
#include< conio.h>

使用名称空间std;

int FindFolder(string，string，int);

#define折叠16
typedef struct
{
字符串FolderName;
int Foldersize;
int FolderFiles;
} DeskFold;

int文件；

int main(int argc，char * argv [])
{
/* DELCARATIONS */
WIN32_FIND_DATA FindFileData;
char cArr [1000];
int icount = 0;
int i;
字符串sTmp;

HWND hwnd;
HANDLE hFind;

向量< DeskFold> MyVect;
DeskFold SObj;

/*查找桌面的路径*/
SHGetSpecialFolderPath(hwnd，cArr，CSIDL_DESKTOP，0);
sTmp.assign(cArr);
sTmp.append("\\");
字符串sPath;
sPath.assign(sTmp);
sPath.append("*");

/*在指定的桌面内查找文件和文件夹*/
hFind = FindFirstFile(sPath.data()，& FindFileData);
做
{
if(FindFileData.dwFileAttributes == FOLD)//仅访问文件夹
{
icount ++;
if(icount> 2)
{
SObj.FolderName.assign(FindFileData.cFileName);
文件= 0;
SObj.Foldersize = FindFolder(sTmp，FindFileData.cFileName，0);
SObj.FolderFiles =文件；
MyVect.push_back(SObj);
}
}
}同时(FindNextFile(hFind，& FindFileData));

FindClose(hFind);


for(i = 0; i< MyVect.size(); i ++)
{
cout<<文件夹名称:"<< MyVect.at(i).FolderName.data()<< endl;
cout<<文件夹大小:"<< MyVect.at(i).Foldersize<< endl;
cout<<文件夹文件:"<< MyVect.at(i).FolderFiles<<< endl<< endl;
}

cout<<"\ n桌面中的文件夹总数:"<< icount-2<< endl;


返回0;
}

int FindFolder(字符串sPath，字符串FileName和int foldersize)
{
int icount = 0;
WIN32_FIND_DATA FindFileData;
HANDLE hFind;
字符串sPath1;
sPath.append(FileName.data());
sPath.append("\\");
sPath1.append(sPath);
sPath1.append("*");
hFind = FindFirstFile(sPath1.data()，& FindFileData);
做
{
foldersize + = FindFileData.nFileSizeLow;
if(FindFileData.dwFileAttributes == 16)
{
icount ++;
if(icount> 2)
FindFolder(sPath，FindFileData.cFileName，FindFileData.nFileSizeLow);
}
其他
文件++;
}同时(FindNextFile(hFind，& FindFileData));

FindClose(hFind);
返回文件夹大小；
}

祝您有美好的一天:)
