How to protect my data files ?

[alan.yap]

I had set up the DS211+ and the file sharing is bothering me. The privilege setting only have read, read/write and no access features only.
1) How can I prevent people from copying my files ? Though they have the read access, they can still copy the files by save as another file name.

2) How can I prevent people from printing the contents ? It suppose to be "read" only.

Anyone any suggestions ?
