What is a .PAF file?
The .PAF file extension stands for Portable Application Installer File. This type of file is used to install applications that can be carried around on a USB flash drive and used on different Windows computers without needing to be installed on those computers. Think of it as carrying your favorite programs, like a web browser (Firefox Portable), an office suite (OpenOffice.org Portable), a file archiver (7-Zip Portable), along with various games, tools, and utilities in your pocket. When you plug the USB drive into a new computer, you can run these programs directly from the USB drive.
To use a .PAF file, you simply need to have the USB flash drive it's stored on. You don't open a .PAF file with a specific program the way you would open a document or an image. Instead, you run it from the USB flash drive to either install or directly launch the portable application on any Windows computer. This makes it incredibly convenient for people who use multiple computers and want to keep their favorite tools and settings with them.
It's important to note that .PAF files are a bit different from another type of portable application file known as .U3P. Both serve similar purposes, but they are based on different technologies. This means that a USB flash drive set up with .PAF files might not work in exactly the same way as one with .U3P files, but the main idea of running applications directly from a USB drive without needing to install them on a computer remains the same.
