摘　　要：恶意删除或数据误删现象时常发生,数据恢复的成败关系到信息的安全。根据基于FAT32系统的删除文件的四种情形,设计基于FAT32的数据恢复算法。系统依据被删除文件的创建时间与该分区或该分区下某一目录中现存文件的创建时间的比较结果来定位被删除文件,读取该文件信息,恢复被删除文件。系统具有简单、易用、灵活、高效等特点。Intentional delete or accidental delete always leads to computer data loss. Data recovery plays an important role in information security protection. An algorithm for data recover based on FAT32 is presented. This system allocates the deleted files by comparing the created time of deleted files with the created time of existing files in the directory or next directory, and then, it accesses the file information to recover the deleted files. The system is simple, easy ,flexible and efficient.
