What is an RBC file?
An .RBC file is most commonly an Educational grading rubric file. Educators use these files in learning management systems like Canvas by Instructure and Rubistar to store structured grading criteria. Internally, these specific rubric files use the standard JSON format.
Because the .RBC extension is shared among different programs, it might also represent a Retrospect Backup Catalog used by Retrospect to index backed-up data, an encrypted tax reporting file associated with the Canada Revenue Agency (CRA), or a Rembo-C Script used by IBM software.
How to open RBC files?
Opening an .RBC file requires the correct software for its specific type. You can view educational rubric files with standard text editors or import them into Canvas. If the file is a Retrospect Backup Catalog, you must use Retrospect Backup & Recovery. If it is a Rembo-C Script, you will need a script editor or the corresponding IBM deployment environment.
Best practices and troubleshooting
If you do not know the origin of your .RBC file, you can inspect it with a text editor. If you see readable text formatted as JSON, it is an educational rubric. If the content looks like unreadable symbols, it is likely a binary backup catalog or an encrypted tax file. Do not modify backup catalogs manually, as this can corrupt your backup index.
Software and tools
Summary
viewer.online/rbc analyzes .RBC files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because educational .RBC files use the known JSON format, viewer.online/rbc can safely open and display them online, eliminating compatibility problems. If your file happens to be a backup catalog or a Rembo-C Script, the viewer will quickly identify the actual format of the user's file.
