When a new file is added to a directory, DO does not show it - at least it's not at the top of the folder it's in when organized by most recent on top. Am I missing a setting somewhere (I've looked), or does it need a fresh reinstallation? Thank you.
Is the file at the top after a refresh? Its modified date may have been set to earlier if you're only looking at the top.
