System partition stores the files of operating system which plays a vitally important role on every computer. All properties of system partition would directly affect the overall performance of computer and the file system of system partition determines the access speed of system over disk data. Moreover, system partition should have sufficient space to store temporary files generated by all kinds of operations. Prompt information would popup to inform user the disk space is insufficient. This time, user should employ a third-party partition manager to increase free disk space on the system partition. Speaking of partition manager, I would like to recommend MiniTool Partition Wizard.
