Problem: How do I batch convert *.docx files to *.doc?
Double-click My Computer or Computer (in Vista) on your desktop.
Double-click the C:\ drive
Click File
> New > Folder and name the folder Temp.
Copy the *.docx files to be converted to this directory.
Next, convert the files by creating a Macro in MS Word 2007.
Open MS Word 2007
Click the Microsoft Office
button
, then click
Word Options.
Click Popular.
Under Top options for working with Word, select the Show Developer tab in the Ribbon check box.
Under the Developer tab, click Macros.
In the Macro
field, enter Conv.

Click Create.
This will open MS Visual Basic.
In window delete all text.
Copy and paste the following text into this window.
Sub conv()
sPath = "C:\Temp\"
sFile = Dir(sPath & "*.docx")
While sFile <> ""
With Documents.Open(sPath & sFile)
.SaveAs FileName:=sPath & Replace(sFile, "docx", "doc"), FileFormat:=0
.Close
End With
sFile = Dir
Wend
End Sub
Click File > Close and Return to Microsoft Word.
This will return you to Word, from here you will run the Macro that will convert the documents in the folder.
In MS Word 2007, under the Developer tab, click Macros.
Highlight the macro you created and click Run.
Open the C:\Temp folder. There now should be 2 of each file - one in *.docx format and the other in *.doc format.
