Portable devices are a very secure and handy way to always carry one's favorite programs and enjoy their functions regardless of the computer they use.
Since there are numerous ways to protect USB devices with portable security tools, one may also install video players that will not require any installation when accessed on any machine.
Most portable video players typically include the most common codecs, so that they will not need to be downloaded separately.
These applications will not depend on any software installed on the computer, so users simply need to connect their devices and launch the video player they have previously copied to their removable device.
