The creation of applications that can be executed from removable storage devices, such as USB drives, without requiring installation on the host operating system is a well-established practice. This functionality allows users to carry and run their preferred software on any compatible computer, leaving no trace of the application on the system after use. A common example is a web browser configured to store all its data within the application folder on a USB drive.
The significance of this practice lies in its ability to enhance user mobility, maintain data privacy, and bypass software installation restrictions imposed by some system administrators. Historically, the demand for such applications arose from the need for users to access their preferred tools across multiple devices without the overhead of repeated installations and potential conflicts with existing software. This need remains relevant in diverse environments, from educational institutions and corporate settings to personal use while traveling.
