The present invention discloses a file caching method and apparatus. The method comprises: obtaining the file size, the access frequency, the average access time interval, and the time difference between the access time closest to the current time and the current time, of each file; according to the file size, the access frequency, the average access time interval, and the time difference of each file, calculating the priority of each file; and based on the priority of each file, caching each file into a cache area with the corresponding accessed priority in a cache pool, wherein the higher priority the cache area in the cache pool has, the more preferably the cache area will be accessed. Thus, according to the file caching method and apparatus disclosed by the present invention, based on the file size, the access frequency, the average access time interval, and the time difference between the access time closest to the current time and the current time, the priority of the file is determined, so that the possibility of the file being accessed can be evaluated more comprehensively, accurate evaluation on the possibility of the file being accessed is ensured, and the cache hit rate is improved.
