Modifying external links

Good day, I have created a course that includes approximately  148 html links to external files (flash files converted to html games).

Now that we are ready to send the final scorm files to the client, I want to change the links so it points to their server... I tried with find/replace .. but it only works on content not "layers"

is there a way to do this? is there an xml file that can be modified externally?

I hope I won't have to go through all the modules, fix and re-export  everything :(

thanks for your help.
