How2 identify incomplete downloads

[pintree3]

Just found out about you guys and love you. B4 I had utorrent and I feel they have gone overboard with what happens in the background.
Anyhow, with utorrent there was an option to add '' !ut " to a download and that is what you saw until the download completed. The advantage of this was that it was easy to identify all incomplete/partial downloads which perhaps you did not want anyway but bits were downloaded as well. So all we had to do was locate such !ut files, search for them and delete them. But it seems to me that one can not do so with Deluge. Incomplete files still have their full extension (mp3, avi. pdf etc.) and the only way to find out if they are good or not is to actually execute them (Or in Windows Explorer no preview is shown). Isn't this important to people?
How do we identify such files (please)? I searched in the Properties and couldn't see how to do so. What of via a plugin? I looked for a plugin to help me with this but couldn't find one. I was hoping someone could direct as to where I could solve this problem via a download or what-have-you.
Thank you

I thought I had forgotten to check the 'notify me when a reply is posted' box since no one has answered but I was wrong.
Hi, is anyone home?
Doesn't this forum have people who can answer questions or perhaps the builders of the program or those taking care of this website?
Doesn't anyone care
Any advice would be greatly appreciated
thank you
