Image File

An image file is used to store an exact replica of a specific set of data on some type of disk drive or in computer RAM. For example: One might keep an “image” of a particular floppy disk stored on a hard drive so it can be retrieved at a later date. The procedure for retrieval usually involves running some software that recreates the image of the original floppy disk on a new disk. Image files are also frequently used with CD writers to prepare data to be written to a CD. In this case all of the desired files are copied into an “image” of the CD that is on a hard drive. Once ready, this image can quickly be written to the recordable CD. Sometimes this procedure is required in order to be able to write a suitable CD, but this will vary upon the software and hardware being used.
