How works BOCLEAN

Hello, i have an installed Boclean and how works this application 90 % of the time the icon in the tray is blinking green and sometimes it’s blinking very fast color red, i

I receive never an message that something is blocked, is there an log where you can see what is blocked.

You can read the online manual for BOC here:

The icon should blink green every ten seconds. When BOC blocks something a message will pop up to tell you and prompt you for further action (remove etc). The only time it will not do this is if you have ticked in configuration for unattended cleanup and removal.
