How so?

I'm sorry, but with this question I'm starting to doubt if you even use Downloads II as administrator or are in any way familiar with it. How about choosing the file from your online download section and then on top choose for "delete"?

I can only compare the filedates of duplicate files in the ftp.

Like I said, I doubt you are using Downloads II like an administrator should. Login to your forums, go to your download section, choose a categorie, you can see all filedates there. Sorry but you should try some things before asking. This is too easy.
Same goes for sorting.... click on the name in the categorie you want things sorted by and you will see them sorted. Filename, date, whatever is displayed there. Then you can make a screenshot or write some things downl

The only serious thing I see here is that your download section is 7 GB and that sorting it out will be a lot of work.
However, every download section needs maintenance, if you only start now to have a look to sort it, you are way too late with it. So in fact this is not a support problem but purely a lack of maintenance problem.

But I hope with you that Jell can think of a way to fix this. It would be nice to have a search and sort thing under "manage files" in the download section. I second that.
