An external storage device, comprising: a decision unit that decides whether a camera that is connected to the external storage device is a compatible camera or a non-compatible camera, the compatible camera storing a first image file including at least a first file name, a first image data and first information and the non-compatible camera storing a second image file including at least a second file name, a second image data and second information; a storage unit that stores the first image file received from the compatible camera or the second image file received from the non-compatible camera as a third image file and management information regarding the external storage device and the camera connected thereto, the third image file including at least a third file name, a third image data and third information; an identification unit that, if the decision unit decides that the camera is the compatible camera, compares the first information included in the first image file with the management information and identifies the first image file to be received from the compatible camera if the first information does not include the management information, and, if the decision unit decides that the camera is the non-compatible camera, compares the second file name included in the second image file with the management information and identifies the second image file to be received from the non-compatible camera if the second file name does not include the management information; a reception unit that receives the first image file identified by the identification unit if the camera is the compatible camera, and receives the second image file identified by the identification unit if the camera is the non-compatible camera; a change unit that creates the third information by adding the management information to the first information included in the first image file received by the reception unit and creates the third image file by changing the first information to the created third information if the camera is the compatible camera, and creates the third file name by adding the management information to the second file name included in the second image file received by the reception unit and creates the third image file by changing the second file name to the created third file name if the camera is the non-compatible camera; and a transmission unit that transmits the management information and the third image file created from the received first image file by the change unit to the compatible camera, and transmits the created third image file with the created third file name to the non-compatible camera, wherein the storage unit stores the third image file created by the change unit.
