摘要： In embodiments of the present invention, a file access request sent by an application to a hard disk is obtained, file information of the accessed file is acquired according to the request, the file accessed by the application is fragmented to obtain at least one file fragment, a condition for copying the file fragment from the hard disk to the cache is set, and the file fragment is copied to the cache when the copying condition is met in a storage unit. Compared with a technical solution in the prior art where the file is copied to the cache, utilization efficiency of the cache is effectively improved.
