Cron Jobs and filters

Hi David,

I am setting up Cron Jobs for all my feeds and have a question.

When a feed exists in the temp folder and then another feed is uploaded to that location, replacing the old feed. When an import function is done, will it update the feed and existing filters, or would a Cron job have to be set up to do the filters after the import?

Or, should a Cron job for the filters import only be done?

Thanks,
Simon.
