The purpose of Scripting FileSystemObject in VB Script is to provide a way to interact with the file system on a computer. With this powerful object, you can perform various tasks such as creating, reading, updating, and deleting files and folders. Let’s dive deeper into the capabilities and benefits of using Scripting FileSystemObject.

What is Scripting.FileSystemObject?
The Scripting.FileSystemObject is a part of the Microsoft Scripting Runtime library that allows you to access and manipulate files and folders through VBScript. It provides a set of methods, properties, and collections to work with the file system.

Why use Scripting.FileSystemObject?
Using Scripting.FileSystemObject in VBScript can greatly enhance your ability to automate file operations. Here are some key advantages:

1. Simplicity: The FileSystemObject provides an easy-to-understand interface for performing file-related tasks. Its methods and properties are intuitive and straightforward.

2. File System Access: With FileSystemObject, you can read from and write to files, create new files or folders, delete existing ones, rename files or folders, check if a file or folder exists, retrieve file attributes (such as size or date), and much more.

3. Automation: By leveraging the power of VBScript along with FileSystemObject, you can automate repetitive tasks involving files and folders. For example, you can write scripts to backup specific files periodically or process large sets of data stored in multiple files.

4. Error Handling: The FileSystemObject provides built-in error handling mechanisms that allow you to gracefully handle exceptions during file operations. This ensures that your script doesn’t crash abruptly in case of errors.

How to use Scripting.FileSystemObject?
To start using Scripting.FileSystemObject in VBScript, you need to create an instance of it:

Set fso = CreateObject(“Scripting.FileSystemObject”)

Once you have the FileSystemObject instance, you can use its methods and properties to perform various tasks. Here are a few examples:

  • Creating a File:
  • “`vbscript
    Set file = fso.CreateTextFile(“C:\path\to\file.txt”)

  • Writing to a File:
  • “`vbscript
    file.WriteLine “Hello, World!”

  • Reading from a File:
  • “`vbscript
    Do Until file.AtEndOfStream
    line = file.ReadLine
    ‘ Do something with the line..

  • Deleting a File:
  • “`vbscript
    fso.DeleteFile “C:\path\to\file.txt”


In summary, Scripting.FileSystemObject is an essential tool for VBScript developers who need to interact with the file system. Its simplicity, powerful capabilities, and error handling mechanisms make it an invaluable asset when it comes to automating file operations. Whether you need to create, read, update, or delete files and folders, FileSystemObject provides the necessary methods and properties to get the job done efficiently.

So start exploring Scripting.FileSystemObject in your VBScript projects and unlock the full potential of file system manipulation!
