En Windows 7 y Windows Vista incluye una funcionalidad integrada en los Administradores de discos para reducir y ampliar las particiones. No más utilidades de terceros

Para llegar a esta utilidad, abra el Panel de control, y escriba en el cuadro de búsqueda .”particiones  o partition” segun el idioma de su SO. inmediatamente puede ver el enlace como en la imagen de abajo:

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.
