What is a .DDI file extension?

.DDI file extension has been classified as Disk image (ISO) binary Files.

.DDI is DiskDupe disk image

The ddi file extension is related to an old, now no longer available or supported program DiskDupe for MS-DOS and Windows operating systems.

The ddi file contains disk image created in the program.

.DDI file format is deprecated and this file format is no longer supported.

Currently, .DDI file type is not actively used and is obsolete. This usually happens with system files in older operating systems, files from long-discontinued software, or with previous versions of some file types (documents, projects, images, etc.) that were replaced in later versions of the original programs.


How to open:

Use DiskDupe to work with *.ddi files.

How to convert:

As far as we know, this .ddi file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.

  2. You need to check the .DDI file for viruses. To do this, you need to scan it with a popular antivirus (Norton, Nod32, Kaspersky, Dr.Web, etc.)
