Windows 7: Cannot extend volume (disk management) although "free space" exists

Cannot extend volume (disk management) although "free space" exists

I have a C: drive which I want to increase in size. Under disk management there is 20GB of "Free space" - (right next to the C: partition). But neither disk management or EASUES partition manager will allow the partition to use this space. How to I change "free space" to "unallocated" so that it can be used ?

Can you post a snip showing what you have? An image makes it easier for us to help you. For example, you said that there was 20GB of free space next to your C: partition. What you didn't say was whether it was to the left or right of it.

If you delete a Logical partition it leaves it's container as Free Space, which can also then be deleted in Disk Mgmt: Rightclick to Delete Volume. You now have Unallocated Space which can be used to create a Primary partition or to extend into from another Primary Partition.

Only Partition Wizard treats Unallocated and Free space the same for all functions. You will need the PW boot disk if you want to resize to the left: Partition Wizard Move/Resize Partition Video Help.

Please post a snip. Here's how.

Please follow this procedure perfectly, no deviations. Thanks, karl

Run disk management:
This method gives you a display without the unneeded navigation pane.
WIN=key with Microsoft logo on top.

Maximize the output of Disk Management:
key combo | X key (selects Maximize) |
Drag the field separators (such as between Status and Capacity) to show entire field.

Make a snapshot:
Drag the cursor around the area you want to snip.
File | Save as | select save location and name | Save

Post the snapshot:

Free space problem

Thank you guys.

I did right click the gree space but when selecting the remove choice I got a warning that that space would then become unusable. That's why I held back and asked for your help. Why do they say "unusable" ? Anyway, I have gone ahead and all is fine ! The C partition has beed extended.
