If you created a virtual disk in the thin format, you can convert it to thick.

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 virtual disk in thick format occupies the entire datastore space originally provisioned to it.
