Somehow I managed to get past the Already Exists issue …

Basically, I did change the default so that I was ALWAYS prompted on where to put the file.
So, the second time I tried this I pointed to where the file was located already.
It did a check and created this item at the bottom of my queued up files.
I did a right mouse click, and did a Forced-re-check.  It climbed to the top quickly, and then was seeding.

BTW, I did get the "Scrape Error" but found another link on how to fix that.

The one thing you will notice is that all the directions for Azureus now are completely out-dated ...
Since it is now Vuze, many of the options have been moved around, so it takes a little longer to find things.

Now if I could better find out how to see if there are no duplicates .....

This is absolutely maddening …  I am trying to follow all the steps that you have laid out for me, and this is not working.
I am obviously doing something wrong, and I don't know what that is.
So ... I have a file in J:\porn\gay\movie-name.avi

I used Vuze to create a new torrent file with the options you've pointed out ...
This creates the .torrent file in the same directory:  J:\porn\gay\movie-name.avi.torrent
I uploaded the image, the description, and the torrent file I just created.

When I download the torrent file I just uploaded, Vuze tells me that the media file already exists.
At that point ... what do I do now?

I want to upload a file first before I dload anything.    Thanks!
