I want that users can't download the pdf files. Only read them but when I select an file it opens in Adobe and ask "Checkout& Open " or "Open".
When I select "Open" I can't download but when I select "Checkout & Open" it asks my username. I can cancel the question and just move on. Then It reopen the file and I can save/download it.
How can it happen? It shouldn't make me download or save it. How can I disable this with Sharepoint and the Adobe ?
