| Zusammenfassung: | A method for file deletion applicable to electronic devices is disclosed. If there is no way to alter the operation of file system, then after setting the file as a deleted file and obtain address of file being set to be deleted by scanning management information of the file system or file stored in the media, then write destructive information such as 0x1 onto the deleted file to destroy data in order to make file content destroyed and unable to be recovered by recovery software. In addition, provided the operation of file system can be altered, and when the user sets the file to be deleted, then set the file as deleted in the management information of file system, and write destructive information onto the file content of the file. |
