What is the difference between computer drive C and drive D?

The difference between computer drive C and D drive: 1. C drive is the main drive letter for program running, while D drive is generally for convenient management; 2. The files in C drive are mainly composed of system folders, while The D drive is one of several logical partitions that have been re-established.

The difference between computer C drive and D drive:

1. The main functions of the two are different

1. C drive is the main drive letter for program running. Disks other than C drive can be used for software installation disks or file storage disks. C drive is generally the default system The computer's operating system is generally installed on this disk by default. This disk must be the primary partition.

2. The D drive is generally divided into the space excluding the C drive for the convenience of management. According to the total size of the hard disk space, plan the size of each partition to be divided. Theoretically, it can be divided into N. According to Alphabetical order downwards.

2. The importance of the two is different

1. Most of the files in the C drive are mainly composed of system folders such as Documents and Settings, Windows, and Program Files. Program The Files folder is generally the default location for installing software, but it is also the location of viruses, so the C drive must be tightly protected. The C drive is extremely important for the single operating system of the local hard disk, so try not to put the C drive when storing data.

2. The D drive refers to one of several logical partitions created within the extended partition after the C drive is carved out and the extended partition is created, including the other E drives and F drives. They are just the names of the hard disk partitions where they are located, and have no special meaning. They are mainly used to distinguish the role of different areas and the content stored.

3. The two levels are different

1. In the hard disk, a primary partition (active partition) is generally divided first , generally speaking, this is the designated C drive. Because this is the primary partition, once the virus invades this partition, it will cause problems, and there are also important sectors such as the partition table, boot area, 1, 0, etc., %*% (some system directories are represented by %*%, Important places such as %SystemRoot%, %temp%, etc. (generally items defined in system variables) need to be protected.

2. The D drive and other drives are all logical partitions. The position equivalent to the C drive is ranked first, and the others belong to the second partition. In an NTFS-partitioned hard disk, the first active primary partition of the first hard disk and the system that supports NTFS are defaulted to the C drive during installation, and the rest are logical partitions. Logical disks store various files or programs in categories. This depends on personal preference. For example, the D drive is used to install various applications and games. E disk stores work, study, and materials. The F drive stores entertainment materials such as movies, music, pictures, etc.
