What is an RNC file?

RNC files mostly belong to Oxygen XML Editor by Syncro Soft. RNC files are compact versions of RELAX NG files, which use a schema language for XML.

Main Usage: RELAX NG, or REgular LAnguage for XML Next Generation, is a document-type declaration format used to define the structure of an XML document. The compact version, which is stored as a RNC file, was created to be directly translatable to and from XML while preserving the meaning and structure of the document.
Related File Extensions: RELAX NG schemas are used with XML files for providing supplementary information about the document. While RNC files are the compact form of RELAX NG schemas, they are typically stored as RNG files, which are not compacted. These file extensions are determined by convention and are not required for the file to function as expected. RELAX NG is similar to the W3C XML Schema specification as a document-type declaration format, both of which were developed at around the same time.

How can I open an RNC file?

You need a suitable software like Oxygen XML Editor to open an RNC file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your RNC file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a RNC file directly in the browser:. Just drag the file onto this browser window and drop it.

Associate the RNC file extension with the correct application.
Update your software that should actually open syntax files. Because only the current version supports the latest RNC file format. Search, therefore, e.g. on the Syncro Soft manufacturer website after an available Oxygen XML Editor update.
To make sure that your RNC file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
