A VBS file is a text file containing code written in Visual Basic Scripting Edition (VBScript). VBScript is a scripting language developed by Microsoft that is derived from Visual Basic. VBS files are commonly used for automating tasks within the Windows operating system, such as managing files, interacting with applications, and performing system administration tasks. They can be executed by the Windows Script Host (WSH), which is a built-in component of Windows. VBScript is also used for client-side scripting in web pages, although its use has declined in favor of JavaScript due to security concerns and cross-platform compatibility. VBS files can be opened and edited with any text editor, but they require the WSH or a compatible interpreter to be executed. The language supports variables, loops, conditional statements, and functions, allowing for the creation of complex scripts. Due to its close integration with the Windows operating system, VBScript can access and manipulate various system resources and settings. However, this also makes it a potential target for malicious scripts, so caution should be exercised when running VBS files from untrusted sources.
