I am looking for some software which will protect files/folders from been copied or deleted from a USB or how to protect files/folders from been copied or deleted from USB.

I want to put some files/folders (powerpoint docs) onto a USB and allow somebody to work and save these files/folders but only to save them onto the USB nowhere else i also don't want them to be able to copy the files/folders from the USB or be able to attach these to an e-mail.

If anybody knows of any software like that?  Or if there is a way to protect the files/folders still allowing them to worked on?

Such software cannot exist. If the user has physical access to the USB stick, and plug it into a machine to which they have administrative rights, they can undo any protection a program might place on the data.

You can prevent them from reading the data by encrypting it, but they can still destroy the data.

There are USB sticks which have physical security mechanisms, which do things like not actually connect themselves unless a password is entered. But these are usually all-or-nothing affairs. That is, you get full access to the USB stick, or no access at all.
