the call packZip(barDirectory, output) creates a zip with "/File1", "/File2" and "/baz/File3" files, and calls packZip(bazDirectory, output) and packZip(file3, output) both create a zip with a single file "/File3".

Output stream is closed in the end.

Parameters:

root - root file or directory

output - the zip stream to write to

Returns:

true in case of success, false otherwise
