Can I Merge Two Partitions Separated by a Recovery Partition?

A Recovery Partition stands between the C drive and the Unallocated partition. I want to combine the Unallocated partition and the C disk so that I can create an empty partition for data and shrink it so that 100GB of the C disk and 100GB of the Unallocated partition remain.

According to your description, you want to shrink the C drive to create a 100 GB unallocated space and combine the two non-adjacent free spaces to make a new partition for data. Needless to say, the Windows-based won't allow users to modify the size of the C drive since it contains important files and data about the Windows system. 

That's why you need a versatile and powerful tool - EaseUS Partition Master, which enables users to combine two non-adjacent partitions or allocate free space from any partition. Here is the simple and reliable solution that EaseUS Partition Master provides:
