Abstract: A method and system for changing storage drive contents, including installing a redirection driver in a computer system, wherein the redirection driver redirects access requests directed to a main storage of the computer system to one of the main storage and a temporary storage; copying files from the main storage to the temporary storage; restoring files from a source storage into the main storage by overwriting corresponding files in the main storage; and redirecting, to the temporary storage, requests for access directed to files of the main storage that have been copied to the temporary storage.
