Hi, I just bought an ASUS X555LA laptop with 1TB HDD. I knew that many HDD are partitioned as C:/ and D:/. D:/ usually for Recovery or similar, and are usually way smaller..My old HP is 500GB with 438 on C:/ and only 25GB for D:/ Recovery.... When I got home I noticed that only 371GB is on C:/ and 558 on D:/. I want to make C:/ bigger. and leave D:/ as backup or whatever. I don't have anything on D:/ yet so if I'm going to do this I'd want to do it now to avoid losing anything I might store there. What is the safest and simplest way to do this. I am running Windows 10. Before I do this what are the pros and cons..I don't really know much about using two partitions as I have now. Thank you in advance
