USB applications, more commonly known as USB apps are defined as portable software that solely operates from a USB flash drive rather than its host computer. Portable USB apps have increased in popularity over the years for their on-the-go access and their ability to do similar if not exact applications of a PC or Mac while keeping it close to you at all times. A majority of this USB software is free to download from third party sources.
A flash drive's registry cannot store these software files; otherwise installation is required on the host system. Consequently, software settings must be written to the drive. Temporary files and settings for these applications are not placed on the computer’s drive. Once the thumb drive is removed from the USB port, the software also leaves the computer without a trace.
