Media library and "new files"

i recently bought and setup a wd live tv and i been messing with the dashboard library thing for tv shows.

anyhow i indexed all the files and it says theres 3000 new files because its the first time ive done it but is there an easy way to mark them all as old so that only files recieved after today up as new if there is a way i cant seem to work it out.

or even if in normal folder viewing is there a way to sort by date so only new files apear at the top??

Yes, you can change the NEW indication to show only the files from the previous 24 hours.

It’s done via the SETUP menu.
