What is an RB file?

RB files mostly belong to Ruby by Ruby Community. An RB file is a script containing source code written in Ruby scripting language. A Ruby script is typically used to create plugins or automate repetitive tasks. For example, SketchUp 3D modeling software uses RB scripts as plugins that extend its features. An RB script can also include HTML, CSS, and JavaScript code with embedded Ruby on Rails code for rendering a dynamic web page. Such scripts can be edited with a code editor such as Sublime. Xojo (previously REALbasic) native application development environment uses an RB file to save source code written in BASIC programming language.

How to open RB files

You need a suitable software like Ruby to open an RB 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 RB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a RB file directly in the browser:. Just drag the file onto this browser window and drop it.

RB file extension format:

If you know the file format, you can also find out how to open or edit the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. If there are problems opening a file, you must first determine the file format used. Our examination of the RB files comes to the following conclusion:

The RB file ending covers a large number of different file formats. The two most common formats are as follows:

10% of all RB files start with the bytes class crucial for this file format. These files are text files, so they contain words and text. The files are 73 bytes to 6 KB in size, with a median of 670 bytes. The file type is old but is used even today. The files contain the following words: class and ActiveRecord. Such files are related to controller and order.
10% of all RB files start with the bytes require crucial for this file format. If you open these files in a text editor, you can view and read the content yourself. Most of these files are 220 bytes to 4 KB in size. The following keywords are characteristic: require and File.

All other RB files (80%) have different formats, the following 6 formats can be found: Rocket eBook, shell script and set. These files sometimes refer to schema, items, config, settings, game, item or ruby. If you want to find out what your RB file contains, drag and drop it onto this page.

How to solve problems with RB files

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