A hair transplantation device can include a generally tubular guide configured to locate a hair follicle bulb by sliding over a hair shaft down to an upper surface of a hair follicle. The guide can have a blunt distal end configured not to transect the hair follicle bulb. The hair transplantation device also includes an outer tubular member sized and configured to be advanced around the guide. The outer tubular member has a dilator and a harvester. The device can be used in a follicle transplantation method in which the guide locates a hair follicle bulb, and the outer tubular member is slid over the guide. Once the outer tubular member is aligned with the guide, the harvesting portion is advanced, cutting dermal tissue surrounding the hair follicle. The outer tubular member is then withdrawn with the hair follicle, relocated in a recipient area, and the hair follicle implanted.

In an operation method for processing data file of the present invention, reduced-size images and file icons of small area associated with the reduced-size images are displayed in pairs at predetermined interval between a reduced-size image and a file icon in each pair, and at least the data file is processed with a function as selected or the display position of the reduced-size image is changed by performing drag-and-drop operations on the file icons instead of performing a drag-and-drop operation on the reduced-size image directly as in the conventional method. According to the foregoing arrangement of the present invention, the reduced-size image can be displayed without reducing the size even while a drag-and-drop operation is being performed, and it is therefore possible to identify each data file based on the reduced-size image.
