The phrase "preview my word document" implied to me the actual viewing of the document, full-content, full-scale.
yes , you are right , I need to give a user option to read the content for whatever document he wants to download , but before downloading he can view the word document in embedded page or frame , if he likes the document he can download instead of downloading every document to read the content . you might tell why to view the word document because I have many files I can not describe each one in order to let him understand the content of the file.
thanks a lot
