It seems that this question is a returning one, so here is a more detailed answer.
I have seen on the Autodesk website a program for batch back saving but I wrote my own application for Purge, Zoom to extents and save in the choused format. Depending on the needs I use AutoCAD 2000 format or DXF –depending on the client’s wish.
How to use the program:
Open a drawing, go to Tools>Load applications and locate the lisp file. Drag it in the Startup folder and close the drawing. Now go to File>Open and in the opening window select ALL the files to be back saved. Press the Open button and … wait. The program will open all the selected files and save them next to the original. The filenames are prefixed with "R2000_".
If the files to be back saved are not in the same directory but in subdirectories, use the Windows search to list all the *.dwg files contained within the main directiry (the one containing the sub directories). Select all the files listed and press Enter. It will work if on your computer AutoCAD is associated with the DWG file extension.
Remove the Lisp from the Startup suit.

(defun saveback()
    (command "-purge" "all" "" "n")
    (command "_.zoom" "e")
    (command "_saveas" "2000" (strcat (getvar "dwgprefix") "\R2000_" (getvar "dwgname")))
    (command "close")
    )
  (saveback)

I've just noticed the thread owner is using 2008 LT so won't be able to use lisps

Hi,

get free Autodesk TrueView from http://www.autodesk.com. This lets you batch-convert dwg's with lots of options:

Formats:
convert_format.jpg
Other Options:
convert.jpg

Note that it will automatically do an audit if requested, bind xrefs and remove plotterdefinitions!

Cheers,

Petri

Mahahaavaaha will be happy to read your opinion-in the chat forum. Please post here only if you have something to say or ask about saving drawings in earlier versions.

Sure, that's fine
Go to File Saveas

I could be wrong, but I'm sure you could write all that to a button macro in LT

there's a few suggestions for software that may be helpful in this FAQ
