Question : If folder does not exist, then create one

I use the line of code below in a sub routine that opens Excel from Access and saves it to the file path that I have specified below.  On my form Me.txtSubFolder reflects the sub folder that the file is to be saved under.

1:	xlBook.SaveAs FileName:= “C:\MainFolder\” & Me.txtSubFolder & "\FileName.xlsx"

In the event that the folder name, which is stored as a value in Me.txtSubFolder, does not exist; then I need some code that will create the sub folder and name it after the value specified in Me.txtSubFolder.

Any ideas are greatly appreciated.  Thanks!

Answer : If folder does not exist, then create one

place this in a REGULAR module

Option Explicit
Public Declare Function MakeSureDirectoryPathExists Lib "imagehlp.dll" (ByVal lpPath As String) As Long
---------------------

to use

Call MakeSureDirectoryPathExists("C:\MainFolder\" & Me.txtSubFolder & "\")

this will automatically create the folders if they don't exists.
using this  
     Call MakeSureDirectoryPathExists("c:\a\b\c\d\e\")
it will create all the folders specified in the line.
NOTE* the last character of the line must be a backslash  \
