Extended data:
1, drive C refers to one of the main partitions of computer hard disk, which is generally used for storing or installing systems. For a single operating system installed on the local hard disk, it is the default local system boot hard disk. Most of the files on disk C are mainly composed of documents and system folders such as settings, windows and program files.
2. Drive C is extremely important for the single operating system of the local hard disk, so try not to put drive C when storing data. By default, the personal directory that needs to be removed from drive C is: c: \ documents and settings \ your login account \ documents.
3. In the hard disk, the main partition (active partition) is usually divided first. Generally speaking, this is the marked C disk. Then an extended partition is established, and within the extended partition, several logical partitions are established, namely the following D disk and E disk.
4. The contents of disk C should be hidden as much as possible. Because of the importance of disk C, it is best not to store all kinds of files on disk C at will. The default path of general software is C:\Program Files\, so try to install some files on other disks, otherwise the computer will be slower and slower. Don't just put files or games on the C drive.
