C++ Delete Directory and File

Method 1：Using system Command

#include< stdlib.h > 
#include< stdio.h > 

int main(　) 
{ 
system( "md d://aa//zhao " ); // 在下新建文件夹 
system( "del d://aa//zhao " ); // 删除该文件夹下的所有文件 
}

Method 2：Using DeleteDirectory Function, you should delete files in the directory first.

BOOL CDlgData::DeleteDirectory(char *sDirName)
{
    CFileFind tempFind; 
    char sTempFileFind[200] ;
 
    sprintf(sTempFileFind,"%s\\*.*",sDirName); 
    BOOL IsFinded = tempFind.FindFile(sTempFileFind); 
    while (IsFinded) 
    { 
        IsFinded = tempFind.FindNextFile(); 
 
        if (!tempFind.IsDots()) 
        { 
            char sFoundFileName[200]; 
            strcpy(sFoundFileName,tempFind.GetFileName().GetBuffer(200)); 
 
            if (tempFind.IsDirectory()) 
            { 
                char sTempDir[200]; 
                sprintf(sTempDir,"%s\\%s",sDirName,sFoundFileName); 
                DeleteDirectory(sTempDir); 
            } 
            else 
            { 
                char sTempFileName[200]; 
                sprintf(sTempFileName,"%s\\%s",sDirName,sFoundFileName); 
                DeleteFile(sTempFileName); 
            } 
        } 
    } 
    tempFind.Close(); 
    if(!RemoveDirectory(sDirName)) 
    { 
        return FALSE; 
    } 
    return TRUE; 
}

Method 3：Using SHFileOperation API

Function Prototype：

WINSHELLAPI int WINAPI SHFileOperation(
    LPSHFILEOPSTRUCT lpFileOp 
   );函数删除包含文件的目录

//删除文件夹
SHFILEOPSTRUCT	 FileOp;   
FileOp.fFlags	=	FOF_NOCONFIRMATION;   
FileOp.hNameMappings   =   NULL;   
FileOp.hwnd   =   NULL;   
FileOp.lpszProgressTitle   =   NULL;   
FileOp.pFrom	=   "要删除的目录";   
FileOp.pTo	 =	 NULL;	 
FileOp.wFunc	=   FO_DELETE;	
SHFileOperation(&FileOp);
