8. The electronic device according to claim 1 , wherein the controller is configured to

fluctuate the range of the relevance ratio to be calculated according to a distance between the key object and the first group object, and

extract an item object including an item object with a lower relevance ratio as the distance is smaller, and

wherein the controller is configured to extract only an item object with a higher relevance ratio as the distance is larger.

9. The electronic device according to claim 1 , wherein the controller is configured to

calculate the range of the relevance ratio according to a movement distance of the key object within a display area of the first group object, and

extract an item object including an item object with a lower relevance ratio as the movement distance is longer, and

wherein the controller extracts only an item object with a higher relevance ratio as the movement distance is shorter.

10. The electronic device according to claim 1 , wherein the controller is configured to make the range of the relevance ratio narrower with a longer tapping time.

11. The electronic device according to claim 1 , wherein the controller is configured not to extract the item object in a period from entering of the key object into a display area of the first group object to an elapse of a preset time.

12. An electronic device comprising:

a storage device configured to store files, each of the files corresponding to at least one criterion of a keyword, a numerical value, and a category;

a controller configured to manage the files by a first directory;

a display device configured to display first file-images of the files and a first folder-image of the first directory on a screen, the first folder-image containing the first file-images; and

an input device configured to detect a touch onto the screen,

wherein:

the controller is configured to display a key object-image on the screen;
