What is a portable application?
A portable application (portable app) is a software product designed to be easily moved from one computing environment to another. They include portable versions of regular applications — such as browsers — as well as specialized apps designed to enhance mobile computing. Portable apps are typically open source and either free, low-cost or donation-funded.
Portable apps are created for compatibility with specific operating systems. The portability in portable apps refers to the way they can be physically carried from one place to another via flash memory device, not interoperability among different operating systems (OSes). Software portability — a different concept — involves software that is written so that the source code can be compiled for different platforms.
