I had alerts folder set to 1gb several weeks ago but upped it to 10gb to see if it resolves my problem but it didn't. What's interesting is file size is 9.99gb but size on disk is 29gb In the Alerts folder, the 1 camera have files dated nearly a month out while but the rest have only about a week's ...

I have 11 cameras and 10 of the 11 is only showing up to 6 days worth of alerts I see that the only difference is the one camera that holds the longer alert is set to continous recording while the the rest are continious sub+trigger.
