Bro you nt understood :| what i mean i wana show my ftp upload file in forum post
You won't be able to do that without some sort of modification. But, one idea would be to not have any sort of index.html file in the directory and make sure that you can go straight to the directory in a web browser, and just post a link to the directory in the post.
Like I said, in the posts you want it in, just paste that URL in.
