The RmDir statement is a crucial aspect of  VBA that allows developers to delete directories or folders on a computer. It serves as a useful tool for managing file systems, specifically for deleting unnecessary or obsolete folders. This blog post will delve into the purpose, syntax, and examples of using the RmDir statement in VBA.

VBA RmDir Statement

Purpose of the RmDir Statement

The main purpose of the RmDir statement is to delete directories or folders from a specified location on a computer. It is especially useful for developers who want to automate the process of removing unwanted folders within their code. Additionally, it can serve as a precautionary measure to ensure that sensitive data or files are not left behind in a specific location after a program is run.

Syntax of the RmDir Statement

The basic syntax of the RmDir statement is as follows:

RmDir path [, attributes]

Where path is the name and location of the folder to be deleted, and attributes are optional parameters that specify the file attributes of the folder. The attributes parameter can take one of the following values:

  • vbNormal (0): Normal Folder
  • vbReadOnly (1): Read-only Folder
  • vbDirectory (16): Directory Attribute
  • vbHidden (2): Hidden Folder
  • vbSystem (4): System Folder

The attributes parameter can also be combined using the bitwise operator “OR” | to specify multiple attributes. For example:

RmDir path, vbHidden | vbSystem

This code will delete a hidden and system folder located at path.

Examples of Using the VBA RmDir Statement

Delete a Single Folder:

To delete a single folder using the RmDir statement, you can use the following code:

RmDir "C:\Users\Username\Downloads\Folder1"

This code will delete the folder named “Folder1” located in the “Downloads” folder of the current user’s account.

Delete a Folder with Multiple Attributes:

You can also delete a folder that has multiple attributes. For example, if you want to delete a hidden and system folder, you can use the following code:

RmDir "C:\Users\Username\Downloads\Folder2", vbHidden | vbSystem

Delete Multiple Folders:

Using a loop and the RmDir statement, you can also delete multiple folders at once. For example, if you want to delete all the folders in a specific location, you can use the following code:

Dim folder as String
folder = Dir("C:\Users\Username\Downloads\*", vbDirectory)
Do While Not folder = ""
    RmDir "C:\Users\Username\Downloads\" & folder
    folder = Dir

This code will loop through all the folders in the “Downloads” directory and delete them one by one until there are no more folders left.

Skip Errors and Continue Deleting:

There may be instances where a folder cannot be deleted due to permission or other issues. In such cases, you can add error handling to your code to skip the errors and continue deleting the remaining folders. For example:

Dim folder as String
folder = Dir("C:\Users\Username\Documents\*", vbDirectory)
On Error Resume Next
Do While Not folder = ""
    RmDir "C:\Users\Username\Documents\" & folder
    folder = Dir
On Error GoTo 0

The On Error Resume Next statement will skip any errors that occur and continue with the next iteration of the loop.

Confirm Deletion with Message Box:

To prevent accidentally deleting important folders, you can add a confirmation message box before the RmDir statement. For example:

Dim delete_confirmation
Dim folder as String
folder = "C:\Users\Username\Desktop\Folder3"
delete_confirmation = MsgBox("Are you sure you want to delete " & folder & "?", vbYesNo)
If delete_confirmation = vbYes Then
    RmDir folder
End If

This code will prompt the user with a message box asking for confirmation before deleting the specified folder.

Important Notes and Remarks

  • The RmDir statement can only delete empty folders. If the folder you are trying to delete has files or other subfolders in it, you will receive an error.
  • If the specified folder does not exist, an error will occur. Therefore, it is recommended to check if the folder exists before attempting to delete it.
  • It is important to be cautious when using the RmDir statement, as it permanently deletes folders and their contents without a way to recover them. So, it is always best to have a backup of important folders before running any code that uses RmDir.

In conclusion, the RmDir statement is a powerful tool for managing file systems and deleting folders in VBA. Its simple syntax and various options make it a versatile statement for automatic folder deletion. In this post, we have discussed its purpose, syntax, and provided 5 examples of using it in different scenarios. However, it is always important to use this statement with caution and have a backup of important folders before deleting them.
