Various options:
1. You can just not input your username
2. You can turn of attachment syncing
3. You can set attachment download to "as needed".
1 doesn't exchange data, 2 and 3 make sure data are exchanged but don't limit attachment download.
What's not possible is to only upload but not download _data_
Thank you very much for your help. I will carry on with your recommendations. By any chance you know which one of this options allows my to access to the documents attached to my online library directly from my computer (with internet connection).
Thanks,
