General Function

• Generally, file extensions let your computer know what type of program is necessary to open a file.
  
  

Specific Function

• Files saved with an RBX extension contain programming information that is being worked on. With an RBX file, a programmer can save his progress on a program to prevent work from being lost or to take a break.
  
  

Effects

• When complete, the information in an RBX file functions as a series of instructions that computers follow to complete a task specified by the programmer.
  
  

Sources

• There are three main programs that create RBX files: Rapid Builder, REALbasic and Rails.
  
  

Considerations

• If you attempt to open an RBX file without a program installed that is able to read that type of file, you are likely to receive an error message.
