The rrx file extension is associated with IBM Datacap, IBM's document-capture, high-speed data-extraction, and data-management software for Microsoft Windows.
An rrx file defines the public methods exposed by a COM DLL and the parameters used by those methods. Datacap uses this definition data as part of its internal configuration and integration with COM components.
rrx files are intended for internal use by IBM Datacap on Microsoft Windows and are not normally opened as standalone documents.
Use the file with the Datacap installation or configuration that requires it. Opening it in another program may not provide a meaningful view of its definitions.
Conversion to other formats is not possible.
