1, right-click "My Computer" on the desktop and find "Manage", as shown in the figure:
2. In the "management" dialog box, find "disk management", as shown:
3. Find disk D in Disk Management, as shown in the figure, and compress the space of disk D by 50G.
4. After the above operations are completed, drive C is "expanded", as shown in the figure, 50g.
5. After the expansion is completed, as shown in the figure, compare before and after the expansion.
6. The above is before expansion, and this is after expansion.
The unit of hard disk capacity is megabytes (MB) or gigabytes (GB). At present, the mainstream hard disk capacity is 500 g ~ 2 TB, and the factors affecting the hard disk capacity are the storage capacity per disk and the number of disks. Many people find that the displayed capacity of a computer is often smaller than the nominal capacity of a hard disk, which is caused by the different conversion relationships between units.
In computers, 1GB= 1024MB, while hard disk manufacturers usually convert it according to 1GB= 1000MB. Hard disk is an important part of personal computer to store data, and its capacity determines the capacity of personal computer to store data, which is one of the first parameters that users should pay attention to when purchasing hard disk.
Disk definition:
A device similar to a magnetic tape is also used in the external memory of a computer. A common device is called a disk. The purpose of this is to prevent the surface of the disk from being scratched, resulting in data loss.
File system: A circular disk was once packed in a square sealed box. With disks, it is much more convenient for people to use computers. Not only the data processing results can be stored in the disk, but also a large number of data input into the computer can be stored in the disk, so that these data can be reused and avoid duplication of work. But not long after, people found another problem: people want to store more and more content on the disk, and it is inconvenient to store a lot of information together. This led to the emergence of the file system.
