.DU_ File

The du_ file extension is very rare used for CAB archives also known as Windows Cabinet.

CAB supports compression and digital signing, and is used by a variety of Microsoft installation engines.

How to open:

Use 7-zip to open *.du_ archives.

How to convert:

As far as we know, this .du_ 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.
