Suppose there are two partitions side by side.
Is it possible to claim space for the right partition from the left partition?
Is it possible to claim space for the left partition from the right partition? Is it true that at the beginning of each partition there are always some data unmovable? That is one thing that makes me ask these questions. Or even movable, with current defragmentation tool in Windows, I don't see it can move all the data to the end of a partition and leave free space at the beginning.
Why? How to do these in both Windows 7 and Ubuntu?
