Abstract:
1. A file management system for managing image data as an image data file stored in a directory, wherein said image data is generated by an image pickup apparatus, comprising: a file generator that generates an additional data file related to the image data file but other than the image data file so that the additional data file and the image data file have a same numeral file number and a different extension in the directory; and a file manager that manages the additional data file and the image data file having the same numeral file number as the additional data file, as one object in the directory on the basis of the same numeral file number so that the file manager performs directory management operations on the object itself as one data unit, wherein said file manager is arranged to delete together the additional data file and image data file having the same file number as the additional data file, as one object in such a manner that the file manager deletes none of the additional data file and the image data file having the same number as the additional data file, in a case where at least one of the additional data file and the image data file having the same number as the additional data file has a protection attribute.
