Why need to delete partitions?

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

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.
