Snowden is a top hacker, and moreover experienced with backing up massive amounts of data (he built Epic Shelter).
Yet when he copies the files from the NSA control center in Hawaii to a microSD card, he drag & drops them, resulting (erroneously for even the casual Windows user) in tens of copying dialogues that could be seen at any time and land him in jail.
Is there any reason for Snowden not to copy the files in a more covert manner? He could use the command line and the scene could still show some sort of progress indicator (and he could... just not minimize the window?). Was xcopy removed from those NSA machines? Is this just a necessary goof or plot hole?
