What is the .DDI File Extension?

.DDI File Extension Description:

The file extension .ddi is described as a disk image file that is associated with two software applications; DiskDoubler and DiskDupe. In the context of a disk image file or just plain disk image, the .ddi file extension represents a strict binary copy of the contents of an entire disk or even a drive. Disk images like the file extension .ddi contains all information found in the original disk, including its properties like File Allocation Tables (FAT), volume, and boot sector, attributes and system specific information. Contrary to common misconception, a disk image is not a collection of data but is a replica of the source disk representing every sector. Because these types of files are referred to as raw data, there is a possibility that they can be created with an unknown format, or by an unknown operating system, or like the file extension .ddi, can be read by different applications.

The DiskDoubler works by compressing and decompressing .ddi file extensions automatically, from and to the target hard drive, to allow for more storage space. Diskdoubler is capable of creating self-extracting and even segmented archives that can be transferred with the user of a floppy disk or a modem. The file extension .ddi supported application, is a safe and fast utility for preserving precious system information that can be used as a back up, in case of machine bog down.

DiskDupe also utilizes the file extension .ddi in supporting its professional, high performance, and quality duplication process. The application is an easy and fast method of creating .ddi file extensions simply by inserting the master floppy disk into the drive and loading the contents into the system RAM when the need arises to the hard drive. From this stored information, the application can create multiple .ddi file extension copies without the need to re-insert the master copy. The speed of execution would depend primarily on the amount of data to be transferred, and the formatting process that needs to be undertaken. An advanced formatting procedure is a feature of the program, which can provide additional duplication speed for the user.
