Managing Virtual Machines
102
Virtual hard disks require periodic maintenance procedures to keep disk operations quick and
efficient, similarly to real hard disks. An expanding disk is very size efficient at the beginning
of a virtual machine's life cycle and becomes less and less efficient as time goes on, because
each time writing to the disk is requested, the system allocates new space, and therefore disk
size increases. Deleting files does not reduce the size of a virtual disk image file in the primary
operating system. Eventually, an expanding virtual disk could grow enormously causing a
number of inconveniencies.

Parallels Workstation includes the Disk Compacting Tool which is recommended for all other
guest operating systems. For more information on the Disk Compacting Tool refer to the

Floppy Disks and Disk Images
Parallels Workstation can access real floppy disks, or create and use floppy image files that
appears to virtual machine floppy drive as real diskettes. Floppy disk images used by Parallels
Workstation have the .fdd format. Blank .fdd image can be created by two methods:

using the Recreate button on the Floppy Options (on page 113) tab of the Configuration
Editor,
when adding a floppy drive to a virtual machine use the Add Hardware Wizard (page 128).
An .fdd image of a real diskette can be created using Parallels Image Tool (page 174), a
special tool for creating images of different real media that is installed along with Parallels
Workstation.

CD/DVD Real Discs and Images
Parallels Workstation can access real CD/DVD discs, or create and use CD/DVD images that
appear to the CD/DVD-ROM drive of a virtual machine as real discs. Parallels Workstation uses
CD/DVD discs in .iso format. Images in this format can be created by many applications,
particularly by Parallels Image Tool (page 174), a special tool for creating images of different

There is a set of limitations on using CD/DVD-ROMs in Parallels Workstation in that it allows
the use only of single-session CD and DVD-ROMs. Multisession disks cannot be handled.
Sound from audio CDs cannot be reproduced. Neither CD nor DVD discs can be written.
