Wherein, the target object includes, for example, files, images, videos, music or texts, Uniform Resource Identifier (UniformResourceIdentifier, URI) resources, and the like.

Exemplarily, the user initiates a processing request to the first target APP. The first target APP is, for example, a file manager, a browser, and other APPs, and the processing request is, for example, a request to open a file.

URI resources refer to resources available on the network, including, for example, HyperText Markup Language (HyperTextMarkupLanguage, HTML) documents, images, video clips, programs, and the like.

Step 102, the first operating system obtains the MIME type corresponding to the target object according to the processing request.

A Multipurpose Internet Mail Extensions (Multipurpose Internet Mail Extensions, MIME) type is an expression method used to describe a type of a file, and it divides files into multiple types to facilitate unified management thereof.

The MIME type specifies the type name, description, icon information, etc. of the file, and at the same time specifies the opening method of the file by integrating with the .desktop application description file.

Optionally, the Linux APP can register the MIME types that the APP can handle with the Linux system through the MIMETYPE keyword in the .desktop file.
