Free portable program preventing access to non-USB drives, protecting confidential files and preventing malware infections.
MyUSBOnly is a free portable Windows application that restricts access and connectivity to all local, network or removable drives except USB flash drives and external hard drives. It works by disabling all drive letters other than the USB storage devices, preventing access to those drives.
This simple yet effective portable software enhances security when using public computers by limiting access to confidential files stored on internal hard disks. It also reduces the risk of malware infections which spread from fixed and mapped network drives.
MyUSBOnly automatically runs on start up and restricts drive access to only the USB drives plugged in at that time. It allows copying files to and from the USB drives. When the USB device is unplugged or MyUSBOnly is exited, access is restored to all the original local disk drives on the computer.
As it makes no system changes and everything is contained in one portable .exe file, MyUSBOnly is ideal software for use on public-access or borrowed computers to keep files and browsing activities private. It works on any version of Windows.
