Windows 7 and Vista include a built-in functionality in Disk Management to shrink and expand partitions. No more 3rd party utilities needed!
To
get to this utility, open up Control Panel, and type
in partition into
the search box.. you’ll immediately see the link show up:
Shrink
a Partition
In
the Disk Management screen, just right-click on the partition that
you want to shrink, and select “Shrink Volume” from the menu.
In
the Shrink dialog, you will want to enter the amount you want to
shrink by, not the new size. For example, if you want to shrink your
50gb partition by roughly 10gb so that it will now be roughly 40gb,
enter 10000 into the box:
Extend
a Partition
In
the Disk Management screen, just right-click on the partition that
you want to shrink, and select “Extend Volume” from the menu.
On
this screen, you can specify the amount that you want to increase the
partition by. In this case, I’m going to extend it back to the
roughly 50GB size that it was before.
Note
that the extend partition feature only works with contiguous space.
