BOOL FileExists(LPCTSTR lpszFileName, BOOL bIsDirCheck)
{
// A quick'n'easy way to see if a file exists.
DWORD dwAttributes = GetFileAttributes(lpszFileName);
if (dwAttributes == 0xFFFFFFFF)
return FALSE;


if ((dwAttributes & FILE_ATTRIBUTE_DIRECTORY) == FILE_ATTRIBUTE_DIRECTORY)
{
if (bIsDirCheck)
return TRUE;
else
return FALSE;
}
else
{
if (!bIsDirCheck)
return TRUE;
else
return FALSE;
}
}
