USB WriteProtector is a small (444KB uncompressed) and portable (no installation needed) software that runs off your USB drive and prevents files being written to it or modified. It can help protect your drive from those annoying virus that affect portable drives, and it can also save you from accidentally making modifications to files or losing them altogether.
