What Is Microsoft Scripting Runtime VBA?

The Microsoft Scripting Runtime VBA, also known as the Scripting.FileSystemObject, is a powerful library that provides access to the file system and allows you to perform various file-related operations in Visual Basic for Applications (VBA).

The Benefits of Using Microsoft Scripting Runtime VBA

  • Simplicity: The Scripting.FileSystemObject provides a straightforward and easy-to-use interface that allows you to work with files and folders.
  • File Manipulation: With this library, you can create, copy, move, delete, and rename files or folders programmatically.
  • Folder Navigation: You can easily navigate through directories, retrieve folder properties, and perform operations on nested folders.
  • File Access: The Scripting.FileSystemObject enables you to open and read text files or binary files with ease. You can also write data to files or append content to existing files.

Getting Started with Microsoft Scripting Runtime VBA

To use the Microsoft Scripting Runtime VBA library in your VBA project, follow these steps:

  1. Add a Reference: In the Visual Basic Editor (VBE), go to “Tools” > “References” and check the box next to “Microsoft Scripting Runtime”.
  2. Create an Instance: Declare a variable of type FileSystemObject using the “Scripting.FileSystemObject” class.
  3. Start Coding: Utilize the various methods and properties provided by the FileSystemObject class to perform file and folder operations.

Example: Creating a New Folder Using Microsoft Scripting Runtime VBA

Here’s an example that demonstrates how to create a new folder using the Microsoft Scripting Runtime VBA:

Sub CreateNewFolder()
    Dim fso As Scripting.FileSystemObject
    Dim folderPath As String
    ' Create an instance of FileSystemObject
    Set fso = New Scripting.FileSystemObject
    ' Specify the path for the new folder
    folderPath = "C:\NewFolder"
    ' Check if the folder already exists
    If Not fso.FolderExists(folderPath) Then
        ' Create the new folder
        fso.CreateFolder folderPath
        MsgBox "New folder created successfully!"
        MsgBox "Folder already exists!"
    End If
    ' Clean up resources
    Set fso = Nothing
End Sub

In this example, we first declare a variable fso of type Scripting.FileSystemObject. We then specify the desired path for the new folder in the folderPath variable.

The code checks if the specified folder already exists using the FoldersExists method. If it doesn’t exist, we create it using the CreateFolder method. Finally, we display appropriate messages based on whether the creation was successful or if the folder already exists.


The Microsoft Scripting Runtime VBA library provides a convenient way to interact with files and folders programmatically in VBA. By leveraging its capabilities, you can automate file-related tasks and enhance your VBA projects with file manipulation functionalities.

Note: Remember to always handle errors appropriately and release resources when you’re finished using them.
