Summary:The invention discloses a file retrieval method, device and equipment and a readable storage medium, and belongs to the field of computer application. The method comprises the steps of obtaining a file query instruction; According to the file query instruction, retrieving whether file information of a to-be-queried file exists in a memory is retrieved, and if the file information of the to-be-queried file does not exist in the memory, retrieving whether file information of the to-be-queried file exists in memory mapping, Wherein the file information of the to-be-queried file is used for obtaining the file, and the memory mapping is used for mapping the file information in the database into the memory. The speed of searching the file information in the memory and memory mapping is higher than the speed of searching the file information in a database and a file system, the file retrieval is realized through a memory and memory mapping two-stage caching mechanism, and the file retrieval efficiency is improved. 本
