Iphoto: Web Page Created On My Desktop


Dear Friends,
I have Mac OS X.2.8.
I had many important files saved on the desktop. Today I opened my latest photos in iPhoto and ,( just playing) I selected one of the photos , choose Export, clicked the "Web page" tab, and than it asked me where I want to save my new Web page. I answered that I want it to be saved on my desktop and indicated in which folder. Than a problem started: the message said: "this directory is already taken, choose anyway???" and (how stupid of me) I answered YES. Than a magic happened and PUFF! ALL MY FILES FROM THE DESKTOP DISAPPEARED. Now ALL I can see on my desktop is this stupid web page created by iPhoto.. I know that all the documents are somewhere there, but I can not find them !
Please somebody help!
