Alternatively, a separate server (not shown) may collect the terminal information and provide the terminal information to the file information obtaining unit 110.

Here, the terminal information acquired by the file information acquisition unit 110 may be information indicating which application package file is stored in which mobile terminal (S201).

The collected file detecting unit 120 of the application package file collecting apparatus 100 compares the information about the application package file to be collected with the terminal information collected by the file information obtaining unit 110, And acquires file collection object information for a plurality of mobile terminals (10, 20, 30). For example, from among the N mobile terminals, it is possible to determine which terminals the mobile terminal stores a specific application package file (S203).

Next, the package file collecting unit 130 of the application package file collecting apparatus 100 confirms the file collecting object information recognized by the collected file detecting unit 120, and based on the confirmed file collecting object information, And divides the application package file into predetermined units for the corresponding mobile terminal among the mobile terminals 10, 20, and 30 to collect the application package file.

At this time, the package file collecting unit 130 collects data on a binary basis according to the embodiment, and if the predetermined condition is satisfied, it can collect data by changing the file entry unit. 1 and 2 show such an embodiment.

In this case, the binary unit collecting unit 131 divides the application package files stored in the plurality of mobile terminals 10, 20, and 30 into binary units (S205), and the package file combining unit 133 combines The central directory of the application package file is combined using the data collected in binary units by the collection unit 131 (S207).

As illustrated in FIG. 3, the application package file includes a single central directory 310 and a plurality of file entries 320. The central directory 310 includes a plurality of file headers 311, 312, 313, and 314 in which information about each file entry 320 is recorded. Each file entry 320 includes local headers 321, 323, 325, 327 and data 322, 324, 326, 328.

3, information on the file entry 320 is recorded in the file headers 311, 312, 313, and 314 of the central directory 310. Therefore, The structure of the file entry 320 can be known accurately.
