You’ll find several posts describing the procedure for extending the virtual disk on Google. A summary of the most commonly referenced posts is available here.

Best practice: Before you begin extending the VMware virtual disk, create a backup copy so that you can restore it in case of failures.

Extending a virtual disk can be a complex operations for several reason, e.g.,:

1) Windows Primary Partition

The virtual disk that is full happens to contain the boot/primary partition for Windows. The following post will help you build intuition about resizing partitions.

2) Snapshots

Eric Seibert’s posts describe the complexity introduced by snapshots

3) Disk space constraints

There is insufficient disk space available on the physical drive to permit further growth

4) Complex multi-step process

It is a multi step process and involves use of different tools and commands in a specific sequence. Creative individuals have devised workarounds to extend the primary partition for Windows by using Linux boot disks and disk partitioning tools such as GParted, and you have to get this right. Here’s an excellent post describing several different approaches.

Recovering from failures to extend: When things go wrong, it can be very painful. Here are a few real-life experiences to learn from

Windows on Mac: Mac users feel particularly challenged in dealing with the Windows philosophy, arcane commands and foreign behavior. Look at  few Mac forums and you will realize how tough life can get for them
