Why Do You Need to Add Space to C drive

Case 1: "I have an 18GB disk drive that has been split into partitions: C: and D:. C: has about 4GB and D: has about 14GB. However, my C: drive is running out of space. How can I add space to C drive from D?"

Case 2: "I am running windows 2000 server, the C: Drive is only a 4 GB partition and 60GB on its D: Drive. How can I increase C drive space so I can do Windows updates and install a program?"

Case 3: "Well when I reformatted my computer I ended up making 2 partitions. I realized how useless the second one was so I deleted it. How can I now add space to C drive?"

What Is the Best Solution to Increase C Drive Space

For average users who know little about disk management, how to add space to C drive is not an easy task. In fact, there are two solutions: increase space in C drive with Disk Management and EaseUS partition software. But which one is the best? We recommend you the latter one. Why? It is true that Windows built-in Disk Management tool can add space to C drive. But the precondition is that there must be continuous space behind C drive. Otherwise, you cannot increase C drive space with it, like Windows Vista, Windows 2008 or Windows 7 Disk Management cannot move the partition to let continuous space behind the C drive which you want to extend. For this reason, we prefer the much easier way to increase C drive space with a magic partition manager, EaseUS partition software. It can help you do this job in simple steps without data loss.
