Method for verifying embedded file system reliability

The invention provides a validating method of the reliability for the embedded file system. The process includes: it obligates the random size of the memory space in the safety range of the input parameter in the embedded file system and then it writes the random size of the files in the memory space until the space is full. Then it deletes the files according to the random sequence. After it, it will detect if the space, the file list and the data are normal and notes the results. The method also includes the detecting the safety range of the embedded file system inputting parameter, the logic space management security and the haleness in the abnormal condition. The method can help the developer to find the question and modify the design quickly to improve the embedded the file system performance.
