Increasing the Virtual Hard Disk Capacity

If you find that the capacity of your virtual machine's hard disk does not fit your needs anymore, you can increase it using Parallels Image Tool.

To increase the capacity of the virtual hard disk:

Launch Parallels Image Tool.
Specify the source image file of the virtual hard disk in the Source Virtual Disk Image File window. You may type the path and file name or use the Choose button to locate the file.
Note: If you choose a hard disk used by a virtual machine that has snapshots, all the snapshots, except the last one, will be deleted.

Select the Increase the disk capacity option in the Select Action window.
Specify the new capacity for the disk. The Add the unallocated space to the last volume check box, which is selected by default, means that the additional disk space will be added to the last volume. If you clear it, the added space will appear as unallocated space. To allocate this space, you can either create a new partition or expand an existing partition. For instructions on allocating the added space, see the Using the Added Space section of Parallels Image Tool User's Guide.

Usage Tip
If you have one Virtual Disk with 2 partitions c: and e: , and want to expand c: - follow steps bellow:
(D: letter is usually assigned to CD/DVD device)
1. Add new Hard Disk as described in manual
2. In Windows open Disk Management console from Computer Management console
3. Create new partition on newly added disk
4. Copy all data from e: to newly created volume f:
5. Remove e: partition
6. Stop Virtual Machine
7. Use Parallels Image Tool to increase space for Hard Disk 1
8. Disk C: will be increased.

To start the process of increasing the disk capacity, click Start. You can view the operation progress in the Processing the File window. Clicking Cancel terminates the operation.

Note: If the virtual hard disk image file you specified is in the old format, it will be automatically converted to the new format.

After the disk image has been successfully modified, the Execution is Completed window appears. Click Finish to close Parallels Image Tool.
