ELECTRONIC DEVICE AND METHOD FOR OPERATING FILE SYSTEM OF ELECTRONIC DEVICE

According to various embodiments, an electronic device may include a random access memory, a storage, and a processor. The processor may be configured to write a file of an application in the memory in response to a file input request of the application, to monitor a write pattern of the file at a first time of writing the file of the application in the memory, followed by updating the write pattern in the memory, to classify the file as one of a hot file and a cold file based on the write pattern of the file at a second time of copying the file written in the memory to the storage, and to control storing a classification result of the file together with the file in the storage or storing the file in a first area or a second area of the storage based on the classification result of the file. The hot file is a file whose modification and/or deletion occurs frequently compared to the cold file, and the cold file is a file whose modification and/or deletion occurs infrequently compared to the hot file. The write pattern may include a degree of modification of the file.
