这篇博客详细介绍了在Cocos2d-x环境下，如何在win32和Android平台上实现文件夹的创建以及递归删除。提供了对应的C++代码实现，包括创建目录、删除目录、判断文件夹以及递归删除文件夹的功能。

本文介绍了win32、android下文件夹的创建以及递归删除，下述代码都可直接在Cocos中调用

#include <sys/types.h>
#include <sys/stat.h>
#include <errno.h> 
#include <stdio.h>

代码：
//Android or win32 创建文件夹
bool DLManager::createDirectory(const char * path)

#if (CC_TARGET_PLATFORM != CC_PLATFORM_WIN32)
	mode_t processMask = umask(0);

	umask(processMask);
	if (ret != 0 && (errno != EEXIST))

	}

#else
	BOOL ret = CreateDirectoryA(path, NULL);
	if (!ret && ERROR_ALREADY_EXISTS != GetLastError())
