FileSystemObject.CreateFolder to create directory and subdirectories

tigeravatar's looping answer might work, but it's a bit hard to read. Instead of micromanaging the string handling yourself, the FileSystemObject has path manipulation functions available, and recursion is slightly easier to read than a loop.

Here is the function I use:

Function CreateFolderRecursive(path As String) As Boolean
    Dim FSO As New FileSystemObject

    'If the path exists as a file, the function fails.
    If FSO.FileExists(path) Then
        CreateFolderRecursive = False
        Exit Function
    End If

    'If the path already exists as a folder, don't do anything and return success.
    If FSO.FolderExists(path) Then
        CreateFolderRecursive = True
        Exit Function
    End If

    'recursively create the parent folder, then if successful create the top folder.
    If CreateFolderRecursive(FSO.GetParentFolderName(path)) Then
        If FSO.CreateFolder(path) Is Nothing Then
            CreateFolderRecursive = False
        Else
            CreateFolderRecursive = True
        End If
    Else
        CreateFolderRecursive = False
    End If
End Function

Need to create each folder one at a time. You can use code like this to do so:

Sub tgr()

    Dim strFolderPath As String
    Dim strBuildPath As String
    Dim varFolder As Variant

    strFolderPath = "C:\Users\<my_username>\DataEntry\logs"

    If Right(strFolderPath, 1) = "\" Then strFolderPath = Left(strFolderPath, Len(strFolderPath) - 1)
    For Each varFolder In Split(strFolderPath, "\")
        If Len(strBuildPath) = 0 Then
            strBuildPath = varFolder & "\"
        Else
            strBuildPath = strBuildPath & varFolder & "\"
        End If
        If Len(Dir(strBuildPath, vbDirectory)) = 0 Then MkDir strBuildPath
    Next varFolder

    'The full folder path has been created regardless of nested subdirectories
    'Continue with your code here

End Sub
