Create directory in writable path

cocos2d-x C++
#1

Hi,

i want to copy some files from APK to FileUtils::getInstance()->getWritablePath(). To organize them i want to create few directories . Is there a way to do it? I did find anything so far.

maybe it can help you for read and sava you data

string TDInvFileUtils::getFileByName(string pFileName){  
    //get first path
    string path = CCFileUtils::sharedFileUtils()->getWriteablePath() + pFileName;  
    CCLOG("path = %s",path.c_str());  
      
    //create a file point 
    FILE* file = fopen(path.c_str(), "r");  
      
    if (file) {  
        char* buf;  //get string  
        int len;    //get string length 
        /*获取长度*/  
        fseek(file, 0, SEEK_END);   //move to end 
        len = ftell(file);          //get length 
        rewind(file);               //return to begin  
        CCLOG("count the file content len = %d",len);  
        //distribute buff space
        buf = (char*)malloc(sizeof(char) * len + 1);  
        if (!buf) {  
            CCLOG("malloc space is not enough.");  
            return NULL;  
        }  
          
        //read file 
    
        int rLen = fread(buf, sizeof(char), len, file);  
        buf[rLen] = '\0';  
        CCLOG("has read Length = %d",rLen);  
        CCLOG("has read content = %s",buf);  
          
        string result = buf;  
        fclose(file);  
        free(buf);  
        return result;  
    }  
    else  
        CCLOG("open file error.");  
      
    return NULL;  
}  

bool TDInvFileUtils::saveFile(char *pContent, string pFileName){  
    //get save path
    string path = CCFileUtils::sharedFileUtils()->getWriteablePath() + pFileName;  
    CCLOG("wanna save file path = %s",path.c_str());  
      
    //create file point
    //path,modle  
    FILE* file = fopen(path.c_str(), "w");  
    if (file) {  
        fputs(pContent, file);  
        fclose(file);  
    }  
    else  
        CCLOG("save file error.");  
      
    return false;  
}

@yuye

if you want to copy file to:
CCFileUtils::sharedFileUtils()->getWriteablePath() + “filename.txt”;
everything works fine.
But if you want to do the same for:
CCFileUtils::sharedFileUtils()->getWriteablePath() + “/sampleDir/filename.txt”;

FILE* file = fopen(path.c_str(), “w”)
returns null because “/sampleDir/” dont exits in this location.

Yeeep!

I just arrived to this point.
We need the create directory method in FileUtils

If you use the latest from GitHUB you can do this with new features, see: https://github.com/cocos2d/cocos2d-x/blob/v3/CHANGELOG

Awesome thanks!
