When the disk's password is entered, the disk image is "mounted", and made available as a new volume on the computer.

Virtual hard disks are often used in on-the-fly disk encryption ("OTFE") software such as FreeOTFE and TrueCrypt, where an encrypted "image" of a disk is stored on the computer. While Windows versions prior to Windows 7 do not natively support mounting disk images to the files system, several software options are available to do this see Comparison of disc image software.

Software packages for Windows are also sometimes distributed as disk images including ISO images.

The advantage compared with some other technologies, such as Zip and RAR archives, is they do not need redundant drive space for the unarchived data. They are usually opened by directly mounting them without using a real disk.

The images are typically compressed Apple Disk Image (.dmg suffix) files. Disk images may also be needed to transfer software to machines without a compatible physical disk drive.įor computers running macOS, disk images are the most common file type used for software downloads, typically downloaded with a web browser. Efficiency is also increased because there is much less opportunity for human error. These technologies reduce end-user impact and greatly reduce the time and man-power needed to ensure a secure corporate environment.

Some can even be scheduled to update only at night so that machines are not disturbed during business hours. There are several types of software that allow software to be distributed to large numbers of networked machines with little Online data and bootable recovery CD images are provided for customers of certain commercial software companies.ĭisk images may also be used to distribute software across a company network, or for portability (many CD/DVD images can be stored on a hard disk drive). Applications for macOS are often delivered online as an Apple Disk Image containing a file system that includes the application, documentation for the application, and so on. Since the spread of broadband, CD and DVD images have become a common medium for Linux distributions. Virtual drives may also be used as part of emulation of an entire machine (a virtual machine). In addition it may reduce power consumption, since it may allow just one device (a hard disk) to be used instead of two (hard disk plus optical drive).

This may provide advantages such as speed and noise (hard disk drives are typically four or five times faster than optical drives, are quieter, suffer from less wear and tear, and in the case of solid-state drives, are immune to some physical trauma). Using disk images in a virtual drive allows users to shift data between technologies, for example from CD optical drive to hard disk drive. However some software provides virtual CD/DVD drives which can produce new disk images this type of virtual drive goes by a variety of names, including "virtual burner". Virtual drives are typically read-only, being used to mount existing disk images which are not modifiable by the drive. Starting from Windows 8, Windows includes native virtual drive functionality. Some operating systems such as Linux and macOS have virtual drive functionality built-in (such as the loop device), while others such as older versions of Microsoft Windows require additional software. Typical uses of virtual drives include the mounting of disk images of CDs and DVDs, and the mounting of virtual hard disks for the purpose of on-the-fly disk encryption ("OTFE"). An emulated drive is typically created either in RAM for fast read/write access (known as a RAM disk), or on a hard drive. It is also used to make perfect clones of hard disks.Ī virtual disk may emulate any type of physical drive, such as a hard disk drive, tape drive, key drive, floppy drive, CD/ DVD/ BD/ HD DVD, or a network share among others and of course, since it is not physical, requires a virtual reader device matched to it (see below). Disk images became much more popular when floppy disk media became popular, where replication or storage of an exact structure was necessary and efficient, especially in the case of copy protected floppy disks.ĭisk images are used for duplication of optical media including DVDs, Blu-ray discs, etc. The early ones were as small as 5 megabytes and as large as 330 megabytes, and the copy medium was magnetic tape, which ran as large as 200 megabytes per reel. Disk images were originally (in the late 1960s) used for backup and disk cloning of mainframe disk media.
