End Function
'返回布尔值:True 存在，False 不存在，foldername 文件夹
Function FolderExist(foldername As String)
Dim Fso As New FileSystemObject
If Fso.FolderExists(foldername) = True Then
FolderExist = True
Else
FolderExist = False
End If
Set Fso = Nothing
End Function

3、获取驱动器参数:
'返回磁盘总空间大小(单位：M)，Drive = 盘符 A ,C, D ...
Function AllSpace(Drive As String)
Dim Fso As New FileSystemObject, Drv As Drive
Set Drv = Fso.GetDrive(Drive) '得到 Drv 对象的实例
If Drv.IsReady Then '如果该驱动器存在(软驱或光驱里有盘片，硬盘存取正常)
AllSpace = Format(Drv.TotalSize / (2 ^ 20), "0.00") '将字节转换为兆
Else
AllSpace = 0
End If
Set Fso = Nothing
Set Drv = Nothing
End Function
'返回磁盘可用空间大小(单位：M)，Drive = 盘符 A ,C, D ...
Function FreeSpace(drive)
Dim Fso As New FileSystemObject, drv As drive
Set drv = Fso.GetDrive(drive)
If drv.IsReady Then
FreeSpace = Format(drv.FreeSpace / (2 ^ 20), "0.00")
End If
Set Fso = Nothing
Set Drv = Nothing
End Function
