How To Increase the Partition Size in Windows 7

If you have multiple partitions on a hard drive, windows7 will allow you to extend or shrink the size of your partition.

Here are the steps.


Go to the Control Panel.

Step 2:

Select System and Security then Select Administrative Tools

Step 3:

Select Computer Management

Step 4:

Select Disk Management

This image shows just how much room is available to extend the first partition to.

Step 5:

Next start the Wizard.

Now you will notice that on Disk0 I have two partitions, one that is allocated, and one that is unallocated.  However, I can extend the partition on the allocated one.

Step 5

Here is where I will start the wizard to extend the drive partition size.



Note: This format will not remove data from your existing partition, so it is safe. If you feel uncomfortable about doing anything to your partition, you might want to back it up first. This can reduce your anxiety.

The other thing that is worth pointing out is that you can increase your disk size without actually having to buy another disk. So it is a money saver.

Also, remember that this program is a modified partition manager. You don’t need a third party program do your partition updates if you only need to shrink or extend the size of the partition.

Finally, note that while we have talked about increasing the size of a partition, it is also possible to shrink the size of the partition. There is a wizard that will do that as well.
