Embodiments of the present disclosure provide a method, an electronic device and a computer program product for file management. The method includes: generating an extended list based on a path list associated with predetermined files, the extended list comprising a set of paths in the path list that are at least partly the same from a root directory; generating an identifier indicating the extended list; and updating the path list based on the identifier. In this way, the embodiments of the present disclosure accomplish optimization of a path list by creating an extended list, to reduce a number of searching performed based on the path list and thus improve the efficiency of searching a file.
