c++ 遍历文件时出现不读取文件夹的情况

Question

#include <stdio.h>
#include <Windows.h>
using namespace std;
void FindFile(const char* filename)//函数语句：找出全盘文件
{   
    char tempPath[1000] = { 0 };
    sprintf(tempPath, "%s\\*.*", filename);

    WIN32_FIND_DATA finddata;//文件属性
    HANDLE hfile = FindFirstFile(tempPath, &finddata);
    while (1)
    {
        if (finddata.dwFileAttributes == FILE_ATTRIBUTE_DIRECTORY)//文件夹
        {
            if (finddata.cFileName[0] != '.')
            {
                sprintf(tempPath, "%s\\%s", filename, finddata.cFileName);
                printf("%s——————————————————\n", tempPath);
                FindFile(tempPath);
            }
        }
        else//文件
        {
            sprintf(tempPath, "%s\\%s", filename, finddata.cFileName);
            printf("%s****************此处不读\n", tempPath);
        }
        if (FindNextFile(hfile, &finddata) == 0)
            break;
    }
}
int main()
{
    char path[5] = { 0 };
    unsigned alldisk;
    printf("主人：\n正在为您检测U盘的拔插喵喵喵喵喵喵。。。。。。\n");
    while(1)
    {
        alldisk = GetLogicalDrives();
        for (int i = 0; i < 10; i++)
        {
            if ((alldisk & 1) == 1)
            {
                sprintf(path, "%c:", 'A' + i);                
            }
            alldisk = alldisk >> 1;
            }
        if (GetDriveType(path) == DRIVE_REMOVABLE)
            break;
    }
    printf("主人：\nU盘：%s已经插入喵", path);
    FindFile("F:\Documents");


    return 0;
}

文件夹Documents中存在文件，不读取其中的文件。

递归一下

void FindFile(const char* filename)
{
    char tempPath[1000] = { 0 };
    sprintf(tempPath, "%s\\*.*", filename);

    WIN32_FIND_DATA finddata;
    HANDLE hfile = FindFirstFile(tempPath, &finddata);
    if (hfile == INVALID_HANDLE_VALUE)
    {
        printf("无法打开目录: %s\n", filename);
        return;
    }

    do
    {
        if (finddata.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
        {
            if (strcmp(finddata.cFileName, ".") != 0 && strcmp(finddata.cFileName, "..") != 0)
            {
                sprintf(tempPath, "%s\\%s", filename, finddata.cFileName);
                printf("%s——————————————————\n", tempPath);
                FindFile(tempPath);
            }
        }
        else
        {
            sprintf(tempPath, "%s\\%s", filename, finddata.cFileName);
            printf("%s****************此处不读\n", tempPath);
        }
    } while (FindNextFile(hfile, &finddata) != 0);

    FindClose(hfile);
}
