Why need to delete partitions?

Usually, there are 2 reasons why people want to delete a partition in Windows 11, 10, 8, 7. 

● Free up disk space: A partition can take up redundant data and occupy large storage space. For example, some PCs have a recovery partition, and lots of people will copy recovery partition to another drive or USB as a  portable recovery drive and delete the recovery partition later to have some free space. 

● Better manage storage space: It can be harder for disk management when there’re too many partitions on the hard disk. So, many people delete unnecessary partitions, create unallocated space and allocate them to other existing partitions. Before deleting a partition, you can move apps from your current partition to another partition to avoid data loss.

But how to delete partitions? It's not hard once you find the proper solutions. Here, in the following contents, the top 4 practical ways will be introduced to help.

How do I delete a partition in Windows 11, 10, 8, 7?
