Will enter a page called "Computer Management", find the "Disk Management" under the "Storage" in the left directory and select, at this time the interface will appear in the middle of the disk details.
Compress existing partitions. Find the hard disk you need to adjust, you can see the graphical partition diagram. Right click on the partition to be reduced /select compressed volume /software will automatically calculate the size that can be compressed, if the compressible value is relatively small, it is best to defragment /enter a compressed value, click on the compression. After the operation is completed, unallocated space will appear at the back of the original partition.
Create a new partition. Right-click on the unallocated space and select New Simple Volume/Follow Wizard. Enter the parameters such as volume size (partition capacity), drive number, partition format, and so on. Friendly reminder, it is recommended to check the quick format to speed up the formatting.
Resize the partition. Disk management that comes with Windows 7 also allows for partition sizing. Compress as well as partitioning, then right click on the next volume and select Expand Volume. However, this extension is a bit weak and can only extend partitions between unallocated spaces.
Notes
If a drive letter (driver number) is occupied, such as the E drive is occupied by the disc, first change the drive letter of the drive to another drive letter, and then reassign the hard drive partition.
