Portable software refers to applications that can be run directly from a removable storage device, such as a USB flash drive, without needing to be installed on a computer. This allows users to carry their favorite programs and settings with them, making it easy to use the software on different machines without leaving a trace behind. One of the main advantages of portable software is its convenience. Users can access their tools and files on various computers, whether at home, work, or public places. Popular examples of portable software include web browsers like Mozilla Firefox and productivity tools like LibreOffice.
