[Question]/[Request] File IO Exposure

Hello,I have looked up this Tutorial ,but there is a question I can’t understand is how can I create a Blueprint from the file in hard disk , I see the data types you can save to hard disk are all variables , not a Object , I tried to save UObject* to the hard disk by your way , but it seems like the UE4 Engine don’t support it (means the “<<” operator can’t do it).So what should I do,THANKS.
