This article introduces how to merge partitions in Windows Server 2008 R2 with both Windows tool and third party server partition software.
Running Windows Server 2008 for a certain time, many people encountered the problem that C drive runs out of space and "Low Disk Space" warning pops up. In technical forums, many people talk about merging partitions in Windows Server 2008. For example, combine C and D drive together, so free space in D drive will be transferred into C drive. It works if you want to increase C drive space, but the best way is by shrinking and extending partitions. In this article, I'll show you how to combine Server 2008 partitions with Disk Management, how to merge and resize partitions with disk partition editor software.
