ResumoThe Windows operating system uses the file management system to manage the data information in the storage medium. The file management system both FAT32( file allocation table 32)and NTFS( new technology file system) are applied widely in Windows operating system. With the development of information technology,the data deletion by Windows operating system cannot meet the user's requirements of complete and security deletion for the data. According to the characteristics of FAT32 and NTFS Data Management and storage structure,the reason that the windows system data cannot be completely removed is analyzed. By searching the directory and file meta to determine the location of the data in the FAT32 and NTFS file systems,using 0 /1 multiple depth override methods to cover disk data,the algorithm for data securty deletion is designed and corresponding windows application program is developed to realize security deletion based on windows data.
