Moving files - path too deep
I am having probs with my machine which I am putting down to the hard drive being nearly full.
To make space I have bought an external hard drive and am moving some files (eg 10 Gb worth of music).
When I start moving the files it will move 'some' (anywhere from a single track to several albums and come to an abrupt halt with the message
cannot move x the path is too deep.
What does this mean and what can I do about it?
