Why need partition manager for Dell?

Generally, a new Dell windows 7 or windows 8 devices is configured with a boot partition, a recovery partition, and a system partition. Both the boot partition and the recovery partition are without volume table and drive letter so as to highly protect them from amending or attacking while the system partition is configured with “C:” which it’s available. However, C partition for the pre-installed OS is very small by default, so the system partition in your Dell may not meet your needs with years of usage and you will find your Dell becomes slower as soon as your C drive is out of space.

Nowadays, we are so glad to see more and maturer computer technology which make things more easily. There isn’t a need for you to adapt the original way to reinstall the windows operating system to get larger space since there are so many important data and the way is much time-consuming. Instead, you can choose a Dell computer partition manager to help you resize Dell partitions easily and without losing data. For example, you can use AOMEI Partition Assistant to extend C drive so as to solve the problem of full space.

The built-in Disk Management of Dell windows has many limits when you extend C drive: firstly, you should make sure there is an unallocated space; secondly, you should ensure that the unallocated space is adjacent and behind C drive. In this way, you can use DM to merge the unallocated space into C drive so as to extend C drive. Luckily, AOMEI Partition Assistant can help you easily extend C drive no matter where the unallocated space is, or you can directly resize partitions to solve the problem when there is no unallocated space. Next, we will show you how to extend C drive with AOMEI Partition Assistant.
