Expanding virtual disks grow in size as you work with them. Besides applications and their 
data, every disk accumulates temporary files. The Disk Compacting Tool, included in Parallels 
Workstation, cleans up the unused disk space occupied by temporary files, thus reducing the 
size of expanding virtual hard disks. We recommend that you use Disk Compacting Tool from 
time to time to save space on the host hard disk.  

The Disk Compacting Tool processes the following partitions: 

ƒ  volumes located on the expanding virtual hard disks and formatted to Windows file systems 

(FAT 16, FAT 32, and NTFS).  

Note. The Disk Compacting Tool does NOT process: 1) volumes located on expanding virtual 
hard disks but formatted to file systems other than Windows, 2) plain virtual disks. 

In general the compacting procedure consists of two stages that can be performed separately: 

1  A preparation step, performed in the guest OS, when an unused disk space is marked.    

This step can be performed only in those guest OSes where the Parallels Tools Center can 
be installed, i.e. in Windows 95/98/NT/ME/2000/XP/2003 guest OSes. See Installing 
Parallels Tools (page 76) for guidelines on installing Parallels Tools package. 

2  A compacting step, performed in the primary OS, when the unused space is removed.  

This step can be performed in two ways:  

ƒ  Immediately after the preparation step is completed. 

All of the selected expanding virtual disks are compacted in one operation.  

This option is available in those guest OSes where the preparation step can be 
performed, i.e. in Windows 95/98/NT/ME/2000/XP/2003 guest OSes. 

ƒ  When the virtual machine is powered off.   

Compacting is launched for each expanding virtual disk one-by-one. 

This way is available in all guest OSes.  

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

1  In the running virtual machine, open the Parallels Tools Center. See the Parallels Tools 

Center (page 161) topic to learn how to do so.  

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

3  In the Disk Compacting Tool Options (page 167) tab, a table in the Status group displays 

the list of volumes that can be compacted. Select the volumes you want.
