.DDZ File

The ddz file extension is mainly associated with the SCO UNIX, an operating system released in 1989 and later replaced by OpenDesktop and OpenServer systems.

The ddz file stores image of driver stored in Adaptec for disk image format and used in SCO Unix.

This ddz file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

How to open:

These drivers are loaded to SCO UNIX only, no other operating system can handle them.

How to convert:

It does not appear to be possible to convert this file type to anything else.
