PROBLEM TO BE SOLVED: To restore data of fragmented deletion files or a file before overwriting as original continuous data.SOLUTION: This file storage device copies data of a file A in a free space on a hard disk 10 when the file A fragmented and recorded on the hard disk 10 is deleted or overwritten. At this time, since the data of the file A is fragmented and recorded, data of the fragmented files A-1, A-2, A-3 is aligned into continuous data and then copied in the free space. Then, as management information of the free space, information indicating that the files A-1, A-2, A-3 copied in the free space are one continuous file A, is recorded on the hard disk 10. |
