I want to give a USB flash drive to a friend but I don't want him to copy the data in USB or add anything to it is it possible so he could only read the files without the ability to do anything else?

    If you can read a file, you can copy it. – uint128_t Feb 15 '16 at 16:36
  • so there is no way? – Mehdi Zibout Feb 15 '16 at 16:37
  • Short of you looking over his shoulder and holding a bat to his head while he reads the files, I don't so how this could be accomplished. – uint128_t Feb 15 '16 at 16:38

    I don't have a bat, can I use knife or something else? – Mehdi Zibout Feb 15 '16 at 16:39

    Encrypt the files on the drive you do not what anyone to have access to, they can copy them but cannot decrypt the files. – Moab Feb 15 '16 at 22:14

As stated in the comments, the answer is no. If it can be read, it can be copied.

Your goal is to "Prevent data on Flash drive to be copied"

One way is to use third party software likes

http://www.nexcopy.com/usb-copy-protection/

http://www.kakasoft.com/

Now the above will require you purchasing those software. so not sure about budget or how critical the data is

If you goal is simply secure these file

Alternative

one alternative zip these files and password protect them, Again this is not what you asked.

i use 7zip and then just password protect my files
