Is it possible to do this without rebuilding the system?
There's plenty of space, and also files can be taken off for the duration.
Is there free software that can do it - I seem to recall having used Easeus Partition Manager but I think that was on an XP system. I also seem to recall using the Windows 7 Disc Management tool to extend/shrink partitions.
But what I need to do (I think) is to shrink the existing partition from 100% of HDD to, say, 20%. Then create a new partition in the free unallocated space.
Can the Windows 7 tool do that? If not is there a free alternative?
We have more and more laws, and less and less enforcement
