Compacting Virtual Disks

Compacting can be performed only for expanding disks no matter whether they are single-file

disks or split disks. For more information on disks format refer to Virtual Hard Disks (page 19).

Note. Compacting of virtual disks cannot be performed if the virtual machine has the Undo

disks option enabled or if it has snapshots.

In general, the compacting procedure consists of two stages:

1 A preparatory stage, performed in the guest OS. This stage is supported only for Windows

95 /98 /NT /ME /2000 /XP /2003 /Vista guest OSes only after Parallels Tools (page 85) are

installed. All types of partitions: FAT 16, FAT 32, and NTFS, can be processed. During this

stage, the unused space is being cleaned.

2 A compacting stage performed in Mac OS X. This procedure removes clean unused space

from the virtual disk file (only space available at the end of the file). This is available for

virtual machines with any other guest operating system and is performed from

Configuration Editor.

Two-Stage Disk Compacting in Windows Guest OSes

To compact disks in Windows 95 /98 /NT /ME /2000 /XP /2003 /Vista guest OSes:

1 When the virtual machine is running, open the Parallels Tools Center by clicking its icon on

the status bar.

2 In the Parallels Tools Center, open the Disk Compacting Tool tab.

3 On the Disk Compacting Tool Options tab, the table in the Status group displays the list of

volumes (disks and partitions) that you can compact. Note that compacting will be more

efficient, if you select all partitions on the virtual disk.

If you want to perform both stages of compacting at once, select the Execute all stages at

once option.

Click Start. All the selected disks will be processed one-by-one.

Note. The first stage (that is cleaning unused space) may take a significant time.

4 If you have selected the Execute all stages at once option, the second stage starts

immediately after the first. The Disk Compacting Tool pauses the virtual machine, and

Parallels Desktop compacts the virtual disk files in Mac OS X. The Compacting virtual hard

disk dialog is displayed. Click Cancel to stop compacting, in this case, the sizes of virtual

disk files will not be reduced.

When the process of compacting is successfully completed, click OK.

5 If you have NOT selected the Execute all stages at once option.

When the first stage of processing disks is complete, you will be prompted to proceed with

the second stage.

You may select to perform the second stage of compacting later. See One-Stage Disk

Compacting below.
