Ah.
After creating a project, you can create a group by module. All projects can be divided into modules. You can plan the group in your mind. The group name corresponds to the module, for example, I have three modules: home Page, tool, and personal center. Then I will have three groups: home, tools, and center, and their code will correspond to the three groups.
Writing a project will certainly reference a third-party class library, so all the folders used for the third-party class library will be put in a unified group, indicating that only third-party files will be put here.
As for resource image images, folders are also placed in an images group. And so on. This is because if you have a strong professional artist, he will give you a good name and get a good name for each module, so that you can use it directly. If you are a professional artist, he directly gave you such a file: 1.png,2.png,3.png. You won't drag it to the project. First, the artist may be busy at ordinary times. It is also used to save things for graphic purposes. Therefore, the artist gave you a cut chart. Do not use it directly.
