According to an embodiment, an electronic device includes a memory including a database file and at least one processor connected to the memory. The at least one processor may identify damage to the database file while a first application running on the electronic device accesses the database file. The at least one processor may control a second application running on the electronic device to wait without accessing the database file until recovery of the damaged database file is completed. The at least one processor may record recovery state information indicating that the database file is recovered if the recovery of the damaged database file is completed. The at least one processor may control the second application to access the recovered database file based on the recovery state information.

Method for recovering database file in electronic device

An electronic device is provided. The electronic device includes a storage device configured to include a first partition, a second partition, and a third partition, and a processor configured to configure the second partition as a first volume and the third partition as a second volume, and attach or detach the second volume to or from a file system to manage a storage space of the storage device.

Electronic device and operation method of electronic device for managing storage space

An electronic device may include a storage, a memory, and a processor configured to read or write a file from or to the memory. The memory may include a lower file system for compressing and storing a file by using a first partition of the storage and an upper file system for decompressing and storing a file by using a second partition of the storage and/or the lower file system. The processor may copy, to an upper file system of the memory, a first file having an access number greater than a certain level by decompressing the first file in the lower file system, and may control a stackable file system to read the first file from the upper file system and to provide the first file to the application layer based on a request from the application layer being detected with respect to the copied first file.
