What is an .RDB file?
An .RDB file is a database or data archive file. Different software programs use this extension for different purposes. The most common use is a Redis database snapshot. Redis uses .RDB files to save data from memory to a hard drive.
Other programs also use .RDB files. For example, Siemens WinCC uses them for SCADA process data archives. These are often SQLite databases. RetroArch uses them for emulator ROM databases. You might also find an .RDB file used as an R Project lazy-load database, a Microsoft Access Jet database, or a Retrospect Backup Set created by EMC.
How to open .RDB files?
Because the .RDB extension belongs to many different programs, you must know what created your file. You cannot use a single offline program to open all .RDB files. viewer.online/rdb analyzes .RDB files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Software and tools
If your file is a Redis database dump, you need a Redis server or a specialized Redis viewer. If it is an SQLite database from SCADA software, you can use an SQLite browser. If it is an emulator ROM database, you need RetroArch. If it is a backup, you need EMC Retrospect software.
Summary
Because an .RDB file can have many possible meanings, we recommend using a tool to identify the actual format of your file. viewer.online/rdb directly opens and previews .RDB files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
