The file retrieval system includes a write unit, a record unit, and a restoration unit. The write unit writes sections to the clusters. The record unit is for recording section allocation information of the sections to the reserved area, simultaneously during writing of the sections of the file to the clusters. The restoration unit restores data stored in the clusters, according to the section allocation information in the reserved area.
