Not seeing all my files and folders in MyCloud

I had same problem so I read all of this thread with keen interest. (too bad some posters forget that they are flipping off at “volunteer” help)
Anyway, all I want to add is that the very last posts that refer to changing zoom worked for me too but in a funny way… I was at 90%, so tried 75, 50 40 to no avail… BUT when I went to 100% voila…they all appeared (in IE). When I tried firefox, they did all show up but I was persuing the IE fix as that is my preferred browser.
Oh well, other than that I have had no issues with mybook or mycloud. It took some learning only because I would get upset that I file would not upload, only to later learn that it was because the same file was already there (my bad)
