PROBLEM TO BE SOLVED: To provide a system and a method for transparently expanding a nonvolatile storage on a computer system through a link connecting one drive to one or more other drives. SOLUTION: When a user adds a new disk drive, the drive is formatted, but not mounted where the user can see it. The data of a selected file are automatically migrated from its original drive to a new supplementary drive or generated directly on the new supplementary drive and the link is placed on the original volume so as to let the system know that the data are placed actually in another place. In one embodiment, that is carried out through an NTFS reparse point on an NTFS link made in the form of a sparsefile, so that disk space on the original drive can be reused.
