size_t origsize = wcslen(wszName) + 1;

size_t convertedChars = 0;

const size_t newsize = origsize * 2;

char strConcat[] = ".BLC"; // the same file name plus different extension name

size_t strConcatsize = (strlen(strConcat) + 1) * 2;

char *nstring = new char[newsize + strConcatsize];

wcstombs_s(&convertedChars, nstring, newsize, wszName, _TRUNCATE);

strcat_s((char*)nstring, newsize + strConcatsize, ( char*)strConcat);
