Support for Windows XP.
QuickImage™ Windows interface allows you to configure and execute imaging sessions. You're no longer forced to operate while in DOS as you are with other imaging software.

Improved performance allows you to create and restore images faster than ever.
Support for a greater number of CD-R/W drives, including IDE, SCSI and PCMCIA drives.
VF Editor allows you to custom-build your own Virtual Floppy files, removing the need to create and boot from floppy diskettes.
