1. A method for managing a logic to physical (L2P) mapping table of a memory device, comprising:
receiving, from a host device coupled with the memory device, a first configuration indicating that a first file is designated as a hot file;
in response to receiving the first configuration, transmitting a first confirmation to the host device without transmitting a L2P dirty entry notification associated with the first file;
receiving a second configuration corresponding to a second file from the host device;
transmitting the L2P dirty entry notification associated with the second file to the host device based on the second configuration, wherein the L2P dirty entry notification indicates that a L2P entry of the L2P mapping table stored in the host device has become dirty; and
in response to receiving the second configuration, transmitting a second confirmation to the host device.
