What is a disk image?
A disk image file (or simply a disk image) is an exact copy of a disk stored in a file. This file contains
all the information required to clone the original disk; boot sector, FAT, and all files and folders along with
their attributes. See Disk Images Explained for more information about disk image
files.
What is an ISO image file?
An ISO image file is a duplicate copy of a complete CD-ROM disk saved in ISO-9660 format. ISO image files are
widely used for storing CD content and quickly transferring it through the Internet. ISO is a common CD image
format for DOS, Windows (Joliet ISO extension), Linux (RockRidge ISO extension), and other operating systems.
Undisker can create ISO images from CDs, open ISO CD image files, and extract files directly from ISO images.
Can Undisker be used as an ISO extractor?
Yes, Undisker can be used as an ISO extractor. Just open the ISO image and extract its files by dragging
them to Windows Explorer or by using the Extract To menu command. For more information, see Using
Undisker as ISO Extractor.
Can I use Undisker to create ISO files?
Yes, you can create ISO files with Undisker. Simply insert your CD into your CDROM drive, select the Capture
CDROM command from the Image menu and choose a filename for the newly created ISO file. For more information,
see Creating ISO images using Undisker.
Is Undisker compatible with other disk image software?
Yes. Undisker is compatible with all popular disk image software. It can open ISO files, WinImage floppy
disk images (IMA), and HDCopy Pro hard disk images (IMG).
Can Undisker make a floppy disk image?
Yes, Undisker can create floppy disk images of your diskettes. Use floppy disk image files to move your
floppy archive to a safe place like a CD-RW or your hard drive. You can write these floppy images back to diskettes
at any time.
Which floppy disk image formats does Undisker support?
Undisker supports generic IMA and IMG floppy disk image formats.
Can Undisker read hard disk images created by HDCopy or HDCopy Pro?

files created by earlier DOS versions of HDCopy (below 3.0).
Does Undisker support NTFS?
No, the current version of Undisker does not support NTFS file system. This support will be available
in future versions of Undisker.
Can Undisker create a CD image?
Yes, you can use Undisker for creating CD images. Undisker uses the ISO-9660 image file format for creating
CD image files. ISO images created by Undisker are fully compatible with other disk image utilities and CD recording
software.
Can Undisker be used for burning ISO images on CDs?
No, Undisker is a disk image utility, not a CD-recording program. You can use any popular CD-burner software
like Nero Burning ROM or Adaptec EasyCD to record Undisker's ISO file to a CD.
Can Undisker create a boot disk image?
Yes, Undisker can create boot disk images of floppy diskettes, hard disks and bootable CDs (El Torito ISO
extension). Undisker makes no distinction between a bootable or non-bootable disk images—it cimply
creates an exact copy of the source disk.
Can Undisker read Linux ISO images?
Yes, Undisker can open and extract Linux ISO images (both ISO-9660 standard and RockRidge extension).
