Claim:
An electronic apparatus comprising: a communication unit that transmits data to an external apparatus; and a control unit that controls storing the data, wherein said control unit controls said electronic apparatus to start storing fixed size partial data, which is less than all of the data included in a single file, from a first storage unit of the electronic apparatus to a second storage unit of the electronic apparatus before a transmission request is transmitted from the external apparatus after a connection between the electronic apparatus and the external apparatus is established, wherein the single file includes contents data and thumbnail data related to the contents data and is stored in the first storage unit of the electronic apparatus, wherein the fixed size partial data is a part of the data included in the single file stored in the first storage unit of the electronic apparatus, and wherein the second storage unit of the electronic apparatus is able to perform higher speed access than the first storage unit, wherein a size of the fixed size partial data is a predetermined fixed size and said control unit controls said electronic apparatus to store the fixed size partial data from the first storage unit to the second storage unit, wherein each fixed size partial data corresponds to one of a plurality of files stored in the first storage unit and has the predetermined fixed size, and wherein said control unit reads out the fixed size partial data of the file, which corresponds to the request, from the second storage unit in a case that the transmission request is transmitted from the external apparatus, and said communication unit transmits the fixed size partial data read out from the second storage unit to the external apparatus, the fixed size partial data including thumbnail data included in the file.
