root of that problem seems to be the windows path length limitation once again. 255 is the maximal number of caracters allowed, therefore files can not be decoded, they then overload the temp dir and bring trouble. the only way this can be prevented is by shortening the path. the question is how to handle it best: should altbinz warn the user when the desired path exceeds 255 caracters and wait for user input or autoshorten the path on it's own so no user input is neccessary?
