Abstract: A method and an apparatus for accessing a file, and a storage system. The method includes: determining L first-file invoking request messages; separately adding, according to physical sector information in the L first-file invoking request messages, the L first-file invoking request messages to M first-file dispatch queues; and processing a first-file invoking request message included in each first-file dispatch queue, to obtain an invoking request message of each first-file dispatch queue, where the invoking request message is used to access a first file. By means of the method and apparatus for accessing a file and the storage system in the embodiments of the present disclosure, a corresponding dispatch queue is allocated to an invoking request message of a micro file, so that combination processing can be performed on invoking request messages of multiple micro files, and a quantity of times of invoking a micro file is reduced.
