C disk introduction.

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. Program Files folder is generally the default location for installing software, but it is also the location of viruses, so drive C should be strictly protected.
