I have been using Blue Iris happily (and in almost total ignorance) for a couple of years. My server is 'headless', i.e. it's in the Garage, with no monitor attached. It's also a Windows 10 Home license, so I don't even have Microsoft Remote Desktop possibility, so I am using VNC Viewer to remote access it. This makes for a rather laggy user experience, which means that I don't spend more time working on it than I need to. So after initial setup of Blue Iris (and probably a tribute to it's usability), apart from a few tweaks to the motion sensor/object detection/trigger zones & hot spot settings, I have basically totally ignored the program, and 99% of my experience with Blue Iris since then has been via UI3. And this has worked perfectly until I filled up a 4tb hard disk with clips, lost all my clips, and I realised I had no storage strategy 
I am pretty happy with my level of positives vs false positives, and I have a workflow where I review and manually flag interesting alerts via UI3. Some of those alerts have been interesting enough for me to upload to Youtube to share with the family, so I don't feel like I have lost the crown jewels or anything, and I have a couple of years before it will happen again!
So... What I am looking for is basically in line with my rather lazy approach. Keep everything until the disk is basically full, then only delete "old and unflagged". But I can't see a way of achieving this. I can see 'Auto-Queue for backup when flagged', but this seems to want me to use an FTP server. Is there no equivalent "Auto move to a 'keepers' folder when manually flagged" functionality? And if not, is there an indirect way of achieve the same outcome?
p.s. I still really don't fully understand the difference between an 'Alert' and a 'Clip', but my ignorance in that area doesnt seem to have caused me any problems yet... Might be worth bearing that in mind when explaining your strategies though!
Thank you!
