Westudythedesignoffilesystemofsmartcardwithsmallcapacityunderthebackgroundofmulti-application.Basedonstatic file management system,we add dynamic storage free space management utilisation and achieve effective management on free space.The reasonable and effective file system design improves the overall performance of the file system of memory card with small capacity.Through the test it shows that design of the file system structure is reasonable,the storage space allocation and recovery algorithm has higher execution speed.%对多任务应用背景下的小容量智能卡的文件系统设计进行研究。在静态文件管理系统基础上，增加动态存储空闲空间管理方法，实现对空闲空间的有效管理。合理有效的文件系统设计，提高了小容量存储卡文件系统的整体性能。经测试表明，文件系统结构设计合理，存储空间分配和回收算法具有较高的执行速度。
