Why merge partitions without losing data?
A hard drive has to be initialized and partitioned before it can be used. You may
want to merge partitions in following situations.
The HDD or SSD does not partitioned reasonably. For example, C drive for
operating system is not big enough yet the D drive used for data storing somehow
has redundant space. You can move
free space form C drive to D drive, or just merge D drive to C drive to
get a bigger partition.
The hard drive is MBR partition style. On a MBR disk, the maximum primary
partitions number is 4. If you want to create a primary partition when there are
already 4, you have to either merge partitions to reduce the partition number orconvert
MBR to GPT without losing data to break the limit.
There are definitely applications or data on one of the partitions. To save the time
and effort of reinstalling, it is a wise move to merge partition without data
