How to change Bootcamp disk allocation

[PickyBiker]

When I first created Bootcamp on my mac I made the partition too small. Now I have no space on Bootcamp and lots of space on the mac partition.

How to I shrink the mac partition and increase the Bootcamp partition and do it without losing what is already on both partitions?

Thanks

CampTune by Paragon Software can increase or decrease a Boot Camp partition non-destructively.

You are warned that the size can not be changed in the future. Sounds like there is an app that might help you out.
