In order to illustrate the technical solutions described in the present application, specific embodiments are used for description below.

1 is a schematic diagram of the implementation process of the file processing method provided in the first embodiment of the present application. The file processing method is applied to a mobile terminal. As shown in the figure, the file processing method may include the following steps:

Step S101: Obtain an incremental package of the application program.

Wherein, the incremental packet includes a decompression control field, a compression control field, and a copy control field.

In the embodiment of the present application, the mobile terminal may periodically poll to detect whether there is an update of the installed application, and when it detects that at least one of the installed applications has an update, obtain the at least one application from the server or a designated device. The incremental package of each application. For example, the mobile terminal periodically sends update query request information to the designated device. After the designated device receives the update query request information, it detects whether there is an update to the application installed on the mobile terminal. If there is an update, , Then the incremental package of the updated application program is sent to the mobile terminal. Wherein, the application in step S101 refers to an updated application in the application installed in the mobile terminal. The installation package of the application installed in the mobile terminal may be referred to as an old installation package, and the application is updated The latter installation package is called the new installation package, and the incremental package is the difference package between the new installation package of the application and the old installation package, and the new installation package can be obtained based on the difference package and the old installation package. It should be noted that the version of the new installation package is usually higher than the version of the old installation package, and the version of the application can be upgraded from the old version to the new version through the incremental package. The server may refer to the device that generates the incremental package, and the designated device may refer to the device that stores the incremental package.

Step S102: Decompress the incremental package to obtain an incremental file.

Obtaining the target check value of the incremental package from a designated device or incremental package;

If the actual check value of the incremental package is the same as the target check value of the incremental package, determining that the incremental package is successfully verified;

If the actual check value of the incremental package is different from the target check value of the incremental package, it is determined that the incremental package fails to be verified.

In the embodiment of the present application, the target check value of the incremental package can be stored in the incremental package, or the target check value of the incremental package can be stored in the designated device. After the mobile terminal obtains the incremental package, it can From the target check value obtained from the incremental package or the designated device, the mobile terminal calculates the actual check value of the obtained incremental package, and compares the actual check value with the target check value. If the actual check value is If the verification value is the same as the target, it is determined that the incremental package verification is successful and the incremental package obtained by the mobile terminal is correct. The application currently installed on the mobile terminal can be updated according to the incremental package; if the actual verification value is the same as the target If the check value is not the same, it is determined that the incremental package check fails, and the mobile terminal can download the full amount at this time, thereby realizing the update of the currently installed application program of the mobile terminal. Among them, the target check value of the incremental package may refer to the check value of the incremental package obtained from the incremental package or a designated device. For example, after the server obtains the incremental package according to a preset differential algorithm, calculates the value of the incremental package Check value, add the check value to the incremental package, or upload the check value of the incremental package when uploading the incremental package to the specified device. The actual check value of the incremental package may refer to the check value of the incremental package calculated by the mobile terminal, and the calculation of the check value of the incremental package by the mobile terminal may refer to the calculation based on the content of the incremental package other than the check value The check value. Wherein, the above-mentioned check value includes but is not limited to MD5 value, cyclic redundancy check value, etc. The check algorithm used when calculating the actual check value and the target check value is the same.
