SHFileOperation API (RemoveDirectory API 대체 사용)

RemoveDirectory API의 경우 폴더에 하위 구성이 존재할 경우 실패 발생.

SHFileOperation API 사용으로 이를 해결 가능.

SHFILEOPSTRUCT structure

http://msdn.microsoft.com/en-us/library/windows/desktop/bb759795(v=vs.85).aspx

typedef struct _SHFILEOPSTRUCT {
  HWND         hwnd;
  UINT         wFunc;
  PCZZTSTR     pFrom;    // This string must be double-null terminated.
  PCZZTSTR     pTo;      // This string must be double-null terminated.
  FILEOP_FLAGS fFlags;
  BOOL         fAnyOperationsAborted;
  LPVOID       hNameMappings;
  PCTSTR       lpszProgressTitle; 

} SHFILEOPSTRUCT, *LPSHFILEOPSTRUCT;

※ 주의

pFrom, pTo 문자열은 반드시 double-null terminated 이어야 한다. 

Although this member is declared as a single null-terminated string, it is actually a buffer that can hold multiple null-delimited file names. Each file name is terminated by a single NULL character. The last file name is terminated with a double NULL character ("\0\0") to indicate the end of the buffer.

bool foo(const wstring& _path)

{

wchar_t path[MAX_PATH + 1] = {0,};

_snwprintf_s(path, _countof(path), _TRUNCATE, L"%s%c", _path.c_str(), '\0');   // ※ 주의

SHFILEOPSTRUCTW op;

ZeroMemory(&op, sizeof(SHFILEOPSTRUCTW));

op.wFunc = FO_DELETE;

op.pFrom = path;

op.fFlags = FOF_NOCONFIRMATION;

op.fAnyOperationsAborted = FALSE;

int ret = ::SHFileOperationW(&op);

if(op.fAnyOperationsAborted || 0 != ret)

return false;

return true;
