Hi
I think that you are saying that having uploaded the three files once you do not want to have to upload them again.
For example they could be very large files.
I understand that you want to refer to them as Downloads in a separate categoy. This you can do but not automatically.
Let me explain a bit more. A Download consists of at least two parts: the downloadable file and the database entry. The Database entry has things like the name of the Download (the Title), the Alias, who uploaded t , which file symbiol, descriptions, which category, a password if required, the access level, the permissions and so on and so on.
These database entries cannot be made automatically.
When creating a Download in another Category you can select the option 'Or select file from an existing Download'
So what you wish can be done.
However I think you might be asking to automaticaly copy every thing uploaded in a month into an alternate 'monthly' category. Is this to see the most recent uploads? You can of course organise Downloads to be shown in date order and in a variety of other ways.
Perhaps you could explain what you are wnnting the users to see.
Best wishesColin
