Impossible to download
May be this explication ??
"You should have recieved an e-mail about this, but just in case that accidently ended up in your junk mail, let me reinterate – all public files on eSnips are now downloadable!

But if for some reason you don’t want your files downloaded by others (though personally I think it’s awesome), don’t worry, this has no effect on files in Private or Shared folders, and you can still opt out of your public content being downloaded.

All you need to do is to go into the relevant folder, in the “Details” setting, and click the “Edit Details” option over the individual file you’d like to change. Between your popular tags and the Captcha field you’ll see a check box labeled “Download”. Uncheck it, save settings, and go back to your folder to confirm the change. And that’s it!"
