Semiconductor memory card and computer readable program |
摘要 |
The present invention provides a semiconductor memory card which no longer allows an illegal practice of acquiring contents of a deleted file. Here, when a deletion event is generated, a deletion handler gives a priority to a null-clear operation of a file entry and a FAT for a file to be deleted over a null-clear operation to other constituents of the file. A null-clear operation to a file entity of the file is distributed to a plurality of event handlers including the deletion handler.
