Can I secure files/folders on a USB key

[casserced]

I have files and folders I want to put on a USB key to give to someone.
I want to make sure that these files and folders cannot be deleted (the files themselves are secured from editing etc...).
Basically I guess I want the USB to work a bit like a read only disc.
Is there a setting when I transfer files to key or a software.
I do not want to have a password to view/open the files, just to prevent deletion.
Thanks
Cass

Than can be done with NTFS permissions - - I did that to mine.

On your home PC, attach the device and make sure you have access to it.

Then you need a setup like this

your PC, using any LUA/UAC account TAKE OWNERSHIP and set Full control
that should leav only that LUA/UAC account with permissions (ie even Administrator and Administrators groups do not show up.)
Now add the EVERYONE id and set Read/Exec/Traverse​

The results will be
any pc to which it is attached will have access to the files (including the ability to COPY or Execute),
but only your home PC-that specific LUA/UAC user will be able to modify the contents.
