Dim MyDir As New System.IO.DirectoryInfo(MyFolder)
Dim MyInfo As String = MyFolder + "文件夹的大小是：" + CalculateDirectorySize(MyDir, True).ToString() + "字节。"

Dim MySize As Long = 0
'检查包含的所有文件
Dim MyFiles() As System.IO.FileInfo = MyDirectory.GetFiles()

用Directory.CreateDirectory即可创建文件夹：
' 建立目录
If Not Directory.Exists("C:\负屃\" TextBox1.Text) Then '检查文件夹是否存在
Directory.CreateDirectory("C:\负屃\" TextBox1.Text) '不存在，创建文件建夹
End If
你的例子是因为少了一个"\"引起的，正确的如下：
Dim fsotest As New FileSystemObject
If fsotest.FileExists("C:\负屃\" TextBox1.Text) = False Then
fsotest.CreateFolder("C:\负屃\" TextBox1.Text) '这里你少了一个\
End If
MsgBox("创建成功")
tmpstr=""
set fso=createObject("scripting.filesystemObject")
Set dc = fso.Drives
for each d in dc
If d.isReady Then
tmpstr=tmpstr "磁盘" d.DriveLetter ":" vbcrlf _
"可用空间：" (d.AvailableSpace/1024/1024/1024) " GB" vbcrlf _
"空余空间：" (d.FreeSpace/1024/1024/1024) " GB" vbcrlf _
"总空间大小：" (d.TotalSize/1024/1024/1024) " GB" vbcrlf _

一般的VBS程序都是可以写在VB程序里面的 只需要稍加变化 加上些关键字 或者数据类型
如果 你想调用一个VBS程序 也可以使用Shell的方法
