VBA Code to check if folder exist
Validation is one of the important parts of any programming language. As per few studies, 60% of the code is focused on validating input or output.
In this article, we will explain 2 methods to validate if the given folder path is valid or not.
The below VBA function uses the Dir VBA function to validate Folder Path.
VBA Code:- To check if the folder exist
'This function checks if given folder path is valid or not
Public Function CheckFolderExist(strFolderPath As String) As Boolean
'If Dir retunrs blank then it is invalid folder path
If Dir(strFolderPath, vbDirectory) = "" Then
CheckFolderExist = False
MsgBox "Invalid Folder Path!", vbCritical
'Else it is a valid folder path
Else
CheckFolderExist = True
MsgBox "Valid Folder Path!", vbInformation
End If
End FunctionExplanation:Â If the function returns True then it is a valid folder path. If function returns False then it is invalid folder path.

'This function checks if given folder path is valid or not
'Microsoft Scripting Runtime reference is required to run this code
Public Function CheckFolderExist(strFolderPath As String) As Boolean
Dim objFileSystem As FileSystemObject
Set objFileSystem = New FileSystemObject
'If FolderExists function returns True then it is valid folder path
If objFileSystem.FolderExists(strFolderPath) = True Then
CheckFolderExist = True
MsgBox "Valid Folder Path!", vbInformation
'Else it is invalid folder path
