How to add unallocated space from an external hard drive to my Windows 10 hard drive

I have an external hard drive with unallocated space that I'd like to add to my primary hard drive on my Windows 10 PC. What are the steps to accomplish this? I've searched online, but I'm still unsure how to proceed.

    The unallocated space is located in a totally different disk from the target disk, right?

    If that is the issue, I am afraid it is not available to do that.

    The built-in disk management only support to extend the disk space right after the hard drive letter. If the unallocated disk space is in the same disk but it is not after the target drive. We may consider the third party disk tool, you can goolge the related tool such as "disk genius" tool.

    Best Regards,
