Abstract

Provided are a method for providing a portable software computing environment and a portable storage device, which connect a computing environment in a low-speed portable storage device to a computer to provide it to a user. A portable software computing environment is changed into a file image to store the changed file image in a portable storage device. The file image of the portable storage device is copied in the storage of a host computer. An input/output request of an application operating in the portable software computing environment is intercepted, and a file is read from the file image copied in the storage of the host computer or a file is written in the copied file image. Changed information which is temporarily stored is reflected in the file image.
