Blue Iris

Hello, I can no longer delete the photos taken by my camera on the left of the screen, a message appears "Could
not delete 1 item(s); may be protected or in use " but I don't know what to do
THANKS

What have you tried so far to resolve this?

Good evening
nothing because I don't know where to start

Can you add a screen grab so we can see the problem ?

Also try to delete again, and have a look at the Log for error messages.
