You can see "Extend Volume" option under Disk Management of Windows 7. You just need to right click a partition after accessing Windows 7 Disk Management so that you can see the "Extend Volume" option. After click this option, you are able to increase the size of the selected partition. However, the problem is that you may find that the "Extend Volume" option is often grayed out, in which situation you always fail to expand the size of selected partition. Is there anything wrong with the Disk Management? Are you able to fix the problem on Windows 7?
If you doubt why the extend volume is grayed out in Disk Management on Windows 7, probably you do not know how Disk Management works to extend a volume. There are "Extend Volume" and "Shrink Volume" options under Disk Management on Windows 7, with which you are able to resize disk partition without repartitioning hard disk. However, why "Extend Volume" option is grayed out when you attempt to extend C drive or other partitions? Usually, "Shrink Volume" is always available as long as there is free space on the partition you want to extend. The problem is that "Extend Volume" is grayed out. The reason is that you can extend a partition in Disk Management only condition that there is adjacent unallocated space. Simply say, if you want to extend C drive, you must make sure that the unallocated space is behind the C drive. In other words, if there is no unallocated space or the unallocated space is not contiguous to the C drive, the extend volume will show grayed out and stops working.
When Disk Management to extend a partition is not available, is there any other solution for disk partition resizing? The answer is yes! You usually have two solutions to make the extend volume work on Windows 7:
1. Delete the partition between the volume you want to extend and the unallocated space
Since the "Extend Volume" option show grayed out when the unallocated space is not adjacent to the partition you want to extend, you can delete the partition between them to fix the problem. This method is usually not so good because you will lose all data stored on the partition after deleting.
2. Move unallocated volume to the partition you need to expand with partition software

Can You Add New Disk to Extend Windows 7 Partition?
Many users are wondering if they can add a new hard disk to extend partition when it is running on low disk space. If you have ever attempted to add a new disk to expand disk partition, you may know that the answer is no. You can add a new disk for data storage when the original hard drive is full, but you cannot add the new disk space to another hard disk partition.
