请教大家一个菜鸟问题~

如何将一个文件夹里面的全部东西拷贝到另一个文件夹喃?拷贝函数我已经写好了,现在就是不是很清楚如何用递归查找到文件夹里面的所有文件内容
看了有兄弟写的源码,但是我发现我的VC7上面好象没有dirent.h这个头文件

谢谢~~~~~~~~~~`

Dev C++ 测试通过：利用链表实现目录内所有文件列表显示

#include <stdio.h>
#include <dirent.h>
/*#include <alloc.h>*/
#include <string.h>

void main(int argc,char *argv[])
{
DIR *directory_pointer;
struct dirent *entry;
struct FileList
{
char filename[64];
struct FileList *next;
}start,*node;
if (argc!=2)
{
printf("Must specify a directory\n");
exit(1);
}
if ((directory_pointer=opendir(argv[1]))==NULL)
printf("Error opening %s\n",argv[1]);
else
{
start.next=NULL;
node=&start;
while ((entry=readdir(directory_pointer))!=NULL)
{
node->next=(struct FileList *)malloc(sizeof(struct FileList));
node=node->next;
strcpy(node->filename,entry->d_name);
node->next=NULL;
}
closedir(directory_pointer);
node=start.next;
while(node)
{
printf("%s\n",node->filename);
node=node->next;
}
}
}

如果是 VC环境，

瞌睡虫·星辰兄,我就是开始看了你的帖子,但是我发现我的VC7上面好象没有dirent.h这个头文件,如何办喃?我是在vc7上面，但是是编一个控制台程序，不会用到可视化方面的东西，谢谢～～～

顶上去，兄弟伙些，说一下哈，好几下把分结了～
谢谢了～～～～～～
