What is a 2FS file?
Operating system (OS) snapshot saved by Puppy Linux, an easy-to-use Linux variant; stores the state of the OS at a point in time and can be used for resetting the OS back to that state; saved to an external file system partition, since Puppy Linux can run standalone off of a CD or .ISO file.
