An object information processing method includes obtaining an information creation request. The information creation request carries a first address identifier of a target object. The target object includes a subdirectory or a sub-file. The method further includes determining a second address identifier of a parent directory to which the target object belongs according to the first address identifier, searching for an information storage area storing metadata of the parent directory according to the second address identifier, and performing data updating for the information storage area according to the first address identifier to create an association relationship between the parent directory and the target object in the metadata.
