If you created a virtual disk in the thin provision format, you can inflate it to its full size.

This procedure converts a thin disk to a virtual disk in thick provision format.

Procedure

1	Select the virtual machine in the inventory.
2	Click the Summary tab and, under Resources, double-click the datastore for the virtual machine to open the Datastore Browser dialog box.
3	Click the virtual machine folder to find the virtual disk file you want to convert. The file has the .vmdk extension.
4	Right-click the virtual disk file and select Inflate.

The inflated virtual disk occupies the entire datastore space originally provisioned to it.
