.QDD File Extension

The qdd file extension is apparently related to older program called QuickDisk and used for its job files, that contain settings for a disk making operation. As there is several programs bearing the same name, it is hard to identify the one that uses this file type.

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

Currently, .QDD file type is not actively used and is obsolete.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 QuickDisk to work with *.qdd files.

How to convert:

As far as we know, this .qdd 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.
