There is only one file type that uses the .OWX extension:
OutWit Hub Automator File
Automator file created and used by Outwit Hub, an application that extracts and organizes data from online sources; contains information, such as properties and notes, that describes an automator in XML or encrypted format.
Outwit Hub provides automators, which can be scripts, jobs, macros, queries, or scrapers, that enable you to perform different functions. A job is a preset period of time that an action should be performed. A macro is a snapshot of the configuration of the application's extractors that can be replayed with 1 click to perform a specific task. A scraper is a description of the data structure in a page, which defines the markers found in the source code that are around the data you want to extract. And queries are a list of URLs or Query Matrices on which an action can be performed.
NOTE: Before version 5, Outwit Hub used the .XML file extension for automators.
