Thin provisioned C drive Basic volume for sharepoint Virtual Machine

Hi there,
My sharepoint VM has think provisioned C drive (100GB basic volume) this is filling up quickly.  I cannot extend or expand the volume.  I right click on the VM, edit settings, click on the drive and I cannot increase the size (its all grayed out).
I have added another volume D though.  
Need help to expand or extend C.

Do you have any snapshots attached to the disk (you cannot extend when you have a snapshot).

Check for snapshots using this article

HOW TO: VMware Snapshots :- Be Patient

Is the disk IDE? (resize not supported)

V2V using VMware vCenter Converter Standalone 5.1 would be an option to create a clone of the existing VM, but also increase the disk size, and partition size in a single procedure.

I have Vaeem backup program on another server which takes care of backing up.  yesterday it showed a warning in doing a backup of this particular vm (I did not pay attention) at that time.  I will see if the Vaeem snapshot is still under process and let you know.

Here you go, my vm is running on the snapshot.  I want to keep all the latest installed software and everything as of today.  I just want to make myself sure before I click on 'beforeofficeapps' snapshot and delete it.  Will it delete all my existing changes?  sorry I forgot the process.

You cannot extend with a snapshot.

The snapshot must be gone.

Snapshots are not BACKUPS!

Select DELETE ALL and that will merge all the changes to the current parent disk, and the Snapshot will be gone. This could take some time, depending on how large the snapshot is.
