To manually delete files from remote location -- use Remote Host tool window (or Tools | Deployment | Browse Remote Host
if it's not visible) -- navigate and delete any file(s) you want.
For keeping your remote host in sync with local (i.e. to delete remote file as soon as local gets deleted as well) you need to enable automatic upload in Settings | Deployment | Options
, in particular:
- Upload changed items automatically to the default server
- Delete target items when source ones do not exist
Obviously, you need to configure all those options as most suitable to your workflow.
