USB WriteProtector is a small (less than 200 KB) and non-installation tool with which we can protect any files stored on a portable USB stick. With USB WriteProtector we will easily lock and, if necessary, also unlock the possibility of storing data on any portable media that is connected to a computer via the USB connection. This operation is trivially simple and is limited to running the program and choosing one of the available options:

"USB storage protection on" or "USB storage protection off". What is important, by blocking data recording using the tool, we also block the possibility of overwriting or deleting this data. USB WriteProtector will be perfect if you want to lend your flash drive to a friend, but we want the data stored on it not to be lost.
