Data processing method, server, and terminal device

A method, applied to a terminal device, the method comprising:

• receiving an upgrade response from a server, wherein the upgrade response comprises a patch file of a first target application;
• reading at least one piece of retained data from first old file data according to position information of the at least one piece of retained data of a patch file in the first old file data and a data length of the at least one piece of retained data;
• reading newly added data of the same length as the interval length and position information of the at least one piece of retained data in first new file data from the patch file according to an interval length between adjacent retained data in the at least one piece of retained data;
• and
• generating the first new file data of the first target application according to the newly added data, the position information of the at least one piece of retained data in the first new file data, and at least one piece of retained data block.

A terminal device, comprising:

• a processor;
• and
• a memory,
• wherein the memory is coupled with the processor, the memory is configured to store computer program codes, and the processor calls the computer program codes to enable the terminal device to:
• receive an upgrade response from a server, wherein the upgrade response comprises a patch file of a first target application;
• read at least one piece of retained data from first old file data according to position information of the at least one piece of retained data of a patch file in the first old file data and a data length of the at least one piece of retained data;
• read newly added data of the same length as the interval length and position information of the at least one piece of retained data in first new file data from the patch file according to an interval length between adjacent retained data in the at least one piece of retained data;
• and
• generate the first new file data of the first target application according to the newly added data, the position information of the at least one piece of retained data in the first new file data, and at least one piece of retained data block.
