Hello everyone：
I have some PDF files,user can view them in brower,but they are not allowed to download or print them.（hide download and print，let files just can view only）
Is any way to do this in nc20?
That’s an easy task, click on the three dots (...) behind the displayed pdf file name in the files app and select “Download” 
thanks！
but i`d like to know how to hide this “download” option button
(and also I need know how to hide “printer” button in view windows）
I have edited my question to make it more clearly
thanks all the way， j-ed
