摘　　要：用户使用U盘存储编辑文件时,因文件单元大小及存储次序等因素,导致在文件系统FAT32中的存储结构不是连续的,碎片化的保存方式又因U盘的反复插拔或者误操作导致数据的丢失。本文基于Winhex数据恢复软件,模拟仿真U盘中文件碎片化存储现象,深入分析其文件存储的基本原理,并研究其快速恢复其文件的方法。When users use usb flash drive to store and edit files,the storage structure in file system FAT32 is not continuous due to file unit size,storage order and other factors,and the fragmentation of the storage method is due to the usb flash drive repeatedly inserted or mistakenly operated resulting in the loss of data.Based on Winhex data recovery software,this paper simulates the fragmented storage of usb flash disk files,deeply analyzes the basic principle of file storage,and studies the method of fast recovery of files.
