[Pharo-users] WAFile or link to file

Hi, I have a problem with WAFile, upload/download files. Of course i know this link : http://book.seaside.st/book/fundamentals/forms/fileupload but in my project I have to import/export all the datas and files and so I lose my WAFile objects So, is it possible to create a WAFile without the web interface (so without html uploadFile) or do you know how to make a link to an existing file on the server. can you help me ? best regards Renaud Vilain
