I did have a scan interval of 3600 ( this should be seconds or what ?) but i turned it off. My scan type was 2 and i turned it to 0 but unfortunately nothing happens. I did started a scan from the status page but the files that i have deleted are still present.
Is this 0.2.4? If so there is a bug when moving files.
You can always start it with -r, and that will reload the whole db from scratch.
