When you right-click on a file node **Solution Explorer**, the **General** property page under the **Configuration Properties** node opens. It contains the following properties:

- **Excluded From Build**

- **Content** (Applies to UWP apps only.) Specifies whether the file contains content to be included in the app package.

- **Item Type**

The **Item Type** specifies the tool that will be used to process the file during the build process. [Files whose extension is known to Visual Studio](/visualstudio/extensibility/visual-cpp-project-extensibility?view=vs-2019#project-items) have a default value in this property. You can specify a custom tool here if you have a custom file type or wish to override the default tool for a known file type. See [Specifying Custom Build Tools](../specifying-custom-build-tools.md) for more information. You can also use this property page to specify that a file is not part of the build process.

The following illustration shows the property page for a *.cpp* file. The default **Item Type** for this kind of file is the **C/C++ Compiler** (*cl.exe*) and the property page exposes various compiler settings that can be applied to this file only.


The following table lists the default Item Types:
