Also please note that you need more free space in order to be able to run the shrinking process. The shrinking process consists of making a copy of your virtual disk while omitting the zero'd out blocks. So how much extra space you need depends on how you configured the virtual disk for your Virtual Machine.
If your Virtual Disk is a single file, then your free space requirement can grow up-to the full size of that virtual disk. If OTOH you are using the split disk scheme where a virtual disk is sliced into multiple files the maximum free space you need is the maximum size a slice can be. Nowadays there's not a fixed slice size, it depends on how big your virtual disk actually is.
For extra safety I recommend to make sure you have an additional 2GB of free space on top of those requirements as mentioned above. As side note, this also explains why it is generally recommended at the forum by the regulars to use a split disk scheme over single disk files. This same problem also exists when you want to commit snapshots. Before we try to shrink the virtual disk files, we should try to remove any unneeded files from the virtual machine to free space.

TIP: This is one of the reasons that it is better to always split virtual disk files in 2GB parts because the temporary file during the shrink process will be created per 2GB part sequentially which means that less disk space is necessary during the shrink operation. Especially with large virtual disks this makes sense. Once the process is finished the VM is returned to a normal state to work with. As you can see in the screenshot below the disk for the VM I was running is now Breadcrumb Home.
Help for this command can be displayed with the command VMwareToolboxCmd help You can first display available disks using the disk list option. Getting Started Articles. If you want to squish the image size down in linux, you can convert the disk type to the same type after filling the free space with zeroes as shown above. For example:.
Seems to work better for me than the defrag util. Which doesn't seem to do much. Just so people know and to remind myself when I google back to this page! The Mac version accepts both -k and -d parameters. I have run fillzero at level 0, I have copied 4Gb of data and run fill zero on image level 1.

Fred, lifesaver. This was by far the simplest way to shrink the guest disk images. Glag I stumbled on this, thank you.
