C++ recursively deletes a directory instance

This article illustrates the implementation of C++ recursively deleting a directory. Share with you for your reference. Specific methods are as follows:

The usage framework of CFindFile is as follows:

void Recurse(LPCTSTR pstr)  

{  

   CFileFind finder;  

  

   // build a string with wildcards  

   CString strWildcard(pstr);  

   strWildcard += _T("\*.*");  

  

   // start working for files  

   BOOL bWorking = finder.FindFile(strWildcard);  

  

   while (bWorking)  

   {  

      bWorking = finder.FindNextFile();  

  

      // skip . and .. files; otherwise, we'd  

      // recur infinitely!  

  

      if (finder.IsDots())  

         continue;  

  

      // if it's a directory, recursively search it  

  

      if (finder.IsDirectory())  

      {  

         CString str = finder.GetFilePath();  

         TRACE(_T("%sn"), (LPCTSTR)str);  

         Recurse(str);  

      }  

   }  

  

   finder.Close();  

}

The recursive delete code is as follows:

//Loop deletes a directory & NBSP; < br / >
void RecursiveDelete(CString strDir)  

{  

    CFileFind ff;  

    CString strPath;  

    strPath = strDir;  

    if (strPath.Right(1) != '\')  

    {  

        strPath += '\';  

    }  

    strPath += "*.*";  

  

    BOOL bWorking = ff.FindFile(strPath);  

    while (bWorking)  

    {  

        bWorking = ff.FindNextFile();  

  

        // skip . and .. files; otherwise, we'd  

        // recur infinitely!  

        if (ff.IsDots())  

            continue;  

  

        // if it's a directory, recursively search it  

  

        if (ff.IsDirectory())  

        {  

            //Recursive directory & NBSP; < br / >
            CString str = ff.GetFilePath();  

            TRACE(_T("%sn"), (LPCTSTR)str);  

            RecursiveDelete(str);  

            //Delete the directory & NBSP; < br / >
            ::SetFileAttributesA(str, FILE_ATTRIBUTE_NORMAL);  

            ::RemoveDirectory(str);  

        }  

        else  

        {  

            //Delete the file & NBSP; < br / >
            CString str = ff.GetFilePath();  

            TRACE(_T("%sn"), (LPCTSTR)str);  

            ::SetFileAttributes(str, FILE_ATTRIBUTE_NORMAL);  

            ::DeleteFile(str);  

        }  

    }  

  

    ff.Close();  

  

}  

int main(int argc, char *argv[])  

{  

    RecursiveDelete("C:\20_128\");  

    return 0;  

}

Hope that the article described in the C++ programming to help you.
