What does a .vbs file extension indicate?

A file with a .vbs extension indicates that it is a VBScript file. VBScript, or Visual Basic Scripting Edition, is a scripting language developed by Microsoft that is primarily used for automation of tasks in Windows environments. It allows users to write scripts for a variety of applications, such as automating processes in Microsoft Office or controlling system operations.

The use of the .vbs extension signifies that the file contains code that can be executed by the Windows Script Host or through an internet browser that supports script execution. When the file is run, it processes the commands written in the VBScript language, which can include anything from simple commands to complex procedures that interact with the Windows operating system.

Other file types mentioned in the options serve different purposes altogether: for example, the idea of opening a virtual file does not specifically correlate with any standard file naming convention associated with scripting or programming languages. Similarly, a video file would typically have an extension such as .mp4, .avi, or .mov, while batch scripts are commonly recognized by the .bat extension. Thus, identifying the .vbs file extension specifically points to its use as a script written in VBScript.
