Resizing (expanding) an existing Bootcamp partition


I am wondering if I can use Winclone for this purpose (below). And if so, what is the process:

I have a mac with a bootcamp partition of 100 GB. I would like to increase the size of this partition to 120 GB, while saving all of my current applications and documents.

I thought I might be able to partition an external hard dive to 120 GB. I would then save my bootcamp image to this drive and then expand it to fill to 120 GB.

Is this possible? If so, what is the process.

Thank you in advance for any help.

MacBook Pro (mid 2012)
2.6 GHz Intel Core i7
16 GB 1600 MHz DDR3
Mac OS 10.13.2
Windows 7

Yes, you can use Winclone in this way, but it requires that you delete and re-create the partition. Make sure you have a good file-based backup as well as a tested Winclone image before removing the partition. You can also use a utility like iPartition to increase the size after making a backup with Winclone (in case there are issues).


Thank you, Tim.

I looked at iPartition, but unfortunately it doesn’t work with High Sierra.

Do I run Boot Camp Assistant to re-create the partition and then restore using Winclone? Or do I simply partition the mac hard drive into one Mac OS Extended (Journaled) and one FAT32, and then restore the Winclone image?

Thanks again.
