Partitioning allows you to manage your hard drive more efficiently. Your computer views each partition as a separate hard drive, automatically giving it a drive letter, allowing you to conveniently organize your hard drive and maximize the performance of your system. Dividing your hard drive into separate partitions plays an essential role in maintaining your computer-preventing conflicts, protecting data, improving efficiency, and increasing performance. ??PowerQuest's award-winning PartitionMagic 8 allows you to separate data files, operating systems, applications, games, and downloads by creating and resizing partitions quickly and easily, without reformatting your hard drive or harming your data. BootMagic, included with PartitionMagic, enables you to safely load and run multiple operating systems (OSes) on the same computer without conflict. Test a new OS without giving up the stability of the OS you are currently using.
