How does the Win7 system merge disk partitions to merge two or more together?

Before reinstalling the rainforest woodwind Win7 system, the disk partition was performed. After the system was installed, only one disk was found to be only 17.4 GB.

1. Select the “Computer” icon on the desktop, press the right mouse button, and select ““Manage” in the right-click menu bar, as shown in Figure 1:
