How can I protect my pdf file from copying?

 I'm trying to protect my pdf file from copying, but I can't find an option. Can anybody help me?

what is so secreat in your PDF files that you want to prevent them from being copied ?


PDF Creator will not prevent your pdf file from being copied but it will prevent anyone who copied your pdf file from Opening it


All you have to do it to go to Options -> Formats -> PDF -> Security

Enable security Set Open password and the tick box below that you are done.

when you make the pdf file any file that you make will require a password to open

 What is it trying to copy, question marks?
