Abstract: A file management method and a file system are applied to the field of data processing technologies. The file system monitors input/output (IO) access information for operating a file, then determines an IO access mode of the file, determines a corresponding file management policy according to the IO access mode, and finally, when the obtained file management policy is inconsistent with a current management manner of the file, adjusts, according to the determined file management policy, the current management manner of the file, for example, a storage medium and a file management granularity, so as to dynamically adjust the storage medium and the file management granularity of the file according to the IO access mode of the file.

Abstract translation: 文件管理方法和文件系统应用于数据处理技术领域。 文件系统监视用于操作文件的输入/输出（IO）访问信息，然后确定文件的IO访问模式，根据IO访问模式确定相应的文件管理策略，最后，当获取的文件管理策略为 与文件的当前管理方式不一致，根据确定的文件管理策略调整文件的当前管理方式，例如存储介质和文件管理粒度，以便动态地调整存储介质和 文件的文件管理粒度根据文件的IO访问方式。
