Applescript to resave AI files

I want an applescript that will allow me to take all the files in a folder (including subfolders) and resave them in a diffarent format. Specifically I am looking to take Adobe Illustrator files and save them without PDF information. The script will need to diffarentiate between AI CS and earlier formats. It will need to look at file types and only attempt the resave with the appropriate types (ie if there is a text document in the folder I do not want to get errors over it, I just want it ignored) and lastly the new files should be saved in user choice of same location or new one. I have partial code that can be used as referance and should shorten the work needed to less than an hour. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform The final script is expected to run on macs using OSX 10.3.2, illustrator CS, and accessing files on a server.
