Electronic device for selectively compressing and decompressing files based on free space and use frequency

A method performed by an electronic device, the method comprising:

• executing, by the electronic device, a storage device manager;
• periodically checking, by the electronic device, a free space on a file system of a storage based at least on a termination of an application;
• determining, by the electronic device, whether a result of the checking of the free space on the file system indicates that a free space of the storage is equal to or less than a first reference ratio;
• selecting, by the electronic device, and compressing data having a use frequency equal to or less than a predetermined use frequency when the free space of the storage is equal to or less than the first reference ratio;
• managing, by the electronic device, the compressed data by using a list;
• and
• reserving and processing, by the electronic device, a block ensured by compression on the file system,
• wherein the selecting and compressing of the data having a use frequency equal to or less than the predetermined use frequency further comprises compressing the data having a use frequency equal to or less than the predetermined use frequency, and
• wherein the data having the use frequency equal to or less than the predetermined use frequency is data unused for a predetermined period.

One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, cause the electronic device to perform operations, the operations comprising:

• executing, by the electronic device, a storage device manager;
• periodically checking, by the electronic device, a free space on a file system stored on a storage based at least on a termination of an application;
• determining, by the electronic device, whether a result of checking the free space indicates that the free space of a storage is equal to or less than a first reference ratio;
• selecting, by the electronic device, and compressing data having a use frequency equal to or less than a predetermined use frequency when the free space of the storage is equal to or less than the first reference ratio;
• managing, by the electronic device, the compressed data by using a list;
• and
• reserving and processing, by the electronic device, a block ensured by compression on the file system,
• wherein the selecting and compressing of the data having a use frequency equal to or less than the predetermined use frequency further comprises compressing the data having a use frequency equal to or less than the predetermined use frequency, and
• wherein the data having the use frequency equal to or less than the predetermined use frequency is data unused for a predetermined period.
