Remaining files on restore

I noticed that on a config-restore images are still left in "images"-folder, which doesn't exists in the backup anymore (also icons I believe). That happens e.g. when restoring a Windows-image (which includes removed images) and then restore the DO-config.

Not that important, but would be nice if on a restore everything would be deleted if it's not included in the backup (AFAIR folder "scripts" is already working that way).

I suppose you select Replace existing configuration completely when restoring?
