1, first from the computer desktop left feet inside to find "computer" to find the computer name, put the mouse over it, and then right-click to select "Management", and then pop-up the Computer Management dialog box. (for finding the Computer Management dialog box, it's easier to put the mouse on my computer on the desktop, and then right to choose Manage).
2, pop-up Computer Management window, we can see on the left of the "Disk Management" tab, click on the Disk Management tag, on its right side will show the computer disk partition information
3, then we can choose a large free space of the disk compression, for example, we want to adjust some of the disk space in D to C, then we can select the D volume, and then click on the right mouse button, in the pop-up menu choose "Compressed Volume" and then in the input compressed space (MB) Fill in the amount of space to be compressed, if you want to compress out of 50G, fill in the 50gx1024mb=51200m, then we fill in the 51200 can be
4, after the compression, we can see the disk volume will be more than a green partition of the "unpartitioned disk"
Finally we just need to allocate the unpartitioned disk space to C disk, operation steps are: Right click on the need to expand the capacity of the letter, and then in the talk of the menu select "Extended Volume (X)", then the Extended Volume Operation Wizard dialog box interface, we choose to extend to the system disk (C disk) can be, Then click Next to complete the operation.
All right! We have successfully adjusted the size of the C-disk partition, the whole process is not quite simple? If your C-disk partition does not have a good friend also don't worry about reloading the system, repartition the hard drive and so on.
C disk is not enough to use the friend to expand the disk!
