Because when files (including system files) are classified and stored in different partitions, even if a partition is attacked by a virus, the data of other partitions will not be effected. It ensures the security of computer data to a certain extent. 

Besides, managing disks cannot be ignored when you encounter problems such as low disk space warning, slow PC speed, etc. Thus, you may need to manage disk partitions at sometimes.
