Claim Text:
1. A method comprising: first setting a first storage region and a second storage region in a memory; first comparing, by a first processor, a compression target data in a file with data in the first storage region; first creating, by the first processor, a first compression code of the compression target data based on the data in the first storage region when a predetermined first consistency between the compression target data and the data in the first storage region is detected; second comparing, by the first processor, the compression target data with data in the second storage region when the predetermined first consistency between the compression target data and the data in the first storage region is not detected, the compression target data being moved to the second storage region after the second comparing; first storing, by the first processor, the compression target data into the first storage region when a predetermined second consistency between the compression target data and the data in the second storage region is detected; and second creating a second compression code of the compression target data based on the data in the second storage region when a predetermined second consistency between the compression target data and the data in the second storage region is detected based on the second comparing, wherein the first compression code and the second compression code are the same type of code and include an identifier indicating being created based on one of the first comparing and the second comparing.
