Thanks for the replay! Well, in this respect if I make a sync, Tabbles shows me all files double from two different locations: from internal and external HDD at the same time. Im just trying to guess which is one correct / or have a correct location. This issue can be possibly solved if Tabbles will control which files currently are available just by controlling which drivers are currently connected (possibly with some additional checkmark somewhere in menu…). Anyway, again, many thanks for amazing software, which can save my life without any doubts..
