What is an RBK file?
An .RBK file can serve several different purposes depending on the software that created it. Most commonly, it is an app settings and data backup file used by Rethink DNS. Other programs use the .RBK extension for digital rally roadbook files in Rally Navigator or keyboard registration bank files for Casio keyboards. It also functions as a database table rebuild backup in Quicken or dBase software. Historically, Microsoft used the .RBK extension for a Windows 95 Registry Backup File.
How to open RBK files?
Because an .RBK file has multiple possible meanings, you must know which program created it. You can restore app backups directly in Rethink DNS. If it is a roadbook, use Rally Navigator. If it is a report definition, SAP Crystal Reports can open it. If you do not know the origin of your file, viewer.online/rbk analyzes .RBK files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
Do not rename the .RBK extension. This will not change the file format and may break compatibility with the original software. If you suspect the file is a backup, keep a safe copy before you try to import it.
Summary
Because many .RBK files use the known ZIP format, viewer.online/rbk can safely open and display them online, eliminating compatibility problems.
