HANDLE a = CreateFileW((LPCWSTR)u"D:\\OneDrive - 翁悸会\\test2.txt", GENERIC_ALL, FILE_SHARE_READ, NULL, OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);

}
This code can successfully open or create a file anywhere other than my OFB - where, if the file exists, it will return an error code 5, ERROR_ACCESS_DENIED according to https://docs.microsoft.com/en-us/windows/win32/debug/system-error-codes--0-499-
This error happens in all subdirectories in the OFB. On the contrary, even my OneDrive Personal will allow this operation. And of course, I have full access to the OFB - I can normally create or open any file with Windows Explorer.
Either if the file does not exist or the file is not in the OFB, CreateFile succeeds.
Is it a windows bug, or I did something wrong?
