Can I protect a file from being copied off my flash drive?

Question

I have one flashdrive that contains serveral files type. (.mp3, .doc, .bnl)

I need to protect another user to copy file .bnl out of my flashdrive. They just look and open only. For other file types, copying is allowed.

Can I do this?

Answer 1

If you can read it, you can copy it. What you describe cannot be done unless you control the machine they are using to read your drive. Even if you did, you'd have to stop him from snapping photos of the monitor.

Answer 2

SECUDRIVE Contents Guard provides copy protection for files. Once you create a secure image file in your USB flash drive and save files into it, they are prevented from being copied.

A user has to enter a password to access the data. After logging in, the user can read or write it but cannot copy it to the local PC.

For other files that do not need copy protection, you can just save it into the rest area of the USB drive.
