What is an .KUX file?

.KUX is Multimedia data

The kux file extension seems to be mainly related to some older multimedia file format once popular in Asia, perhaps used in the Youku service.

Unfortunately, we could not find any relevant information about this file type.

This kux 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:

Possibly may have been playable only using a specialized media player.

How to convert:

We do not know about any converter for *.kux files at this time. But generally speaking, multimedia files can be usually converted unless they are locked in a proprietary closed format.
