Function delete a Folder or directory with files and subfolders.

There is no API to delete a directory with files and subfolders.

It is the function to delete folders with files using shell operation.

bool DeleteDirectory(LPCTSTR lpszDir)

{

int len = _tcslen(lpszDir);

TCHAR *pszFrom = new TCHAR[len+2];

_tcscpy(pszFrom, lpszDir);

pszFrom[len] = 0;

pszFrom[len+1] = 0;

SHFILEOPSTRUCT fileop;

fileop.hwnd   = NULL;    // no status display

fileop.wFunc  = FO_DELETE;  // delete operation

fileop.pFrom  = pszFrom;  // source file name as double null terminated string

fileop.pTo    = NULL;    // no destination needed

fileop.fFlags = FOF_NOCONFIRMATION|FOF_SILENT;  // do not prompt the user

fileop.fAnyOperationsAborted = FALSE;

fileop.lpszProgressTitle     = NULL;

fileop.hNameMappings         = NULL;

int ret = SHFileOperation(&fileop); 

delete [] pszFrom;  

return (ret == 0);

}

This function return true if it succeed.

error C2664: 'void ATL::CStringT::Format(const wchar_t *,...)' : cannot convert parameter 1 from 'const char [3]' to 'const wc

If you are getting following error:

error C2664: 'void ATL::CStringT::Format(const wchar_t *,...)' : cannot convert parameter 1 from 'const char [3]' to 'const wchar_t *'

Solution1:

In Project Menu select your Project Properties.

In Configuration Properties

Set "Character Set" as "Use Multi-Byte Character Set"

Solution2:
where ever you are declaring "CString" variable add Unicode support.
Example:
CString csStr(_T("")); //_T("") is for unicode support
