Export all MS Access SQL queries to text files

This should get you started:

  Dim db As DAO.Database
  Dim qdf As DAO.QueryDef

  Set db = CurrentDB()
  For Each qdf In db.QueryDefs
    Debug.Print qdf.SQL
  Next qdf
  Set qdf = Nothing
  Set db = Nothing

You can use the File System Object or the built-in VBA File I/O features to write the SQL out to a file. I assume you were asking more about how to get the SQL than you were about how to write out the file, but if you need that, say so in a comment and I'll edit the post (or someone will post their own answer with instructions for that).

Hope this helps.

Public Function query_print()
Dim db As Database
Dim qr As QueryDef

Set db = CurrentDb

For Each qr In db.QueryDefs
  TextOut (qr.Name)
  TextOut (qr.SQL)
  TextOut (String(100, "-"))
Next
End Function

Public Sub TextOut(OutputString As String)

    Dim fh As Long

    fh = FreeFile
    Open "c:\File.txt" For Append As fh
    Print #fh, OutputString
    Close fh

End Sub
