Is is possible to delete a folder?

Hi again

I see that I get a lot of Spam in a particular folder. The old mail I
had in this folder contained a lot of attachemnts etc. so I think that
may be the reason. I would like to retrain Ifile with only a subset of
this folder, but is this possible. Do I have to start from scratch and
train each folder again except this?

Thanks in advance.
