Partial classes should be used when you want to split the implementation of a class across multiple code files. Typically, this approach is warranted when you have a class that is partially user-defined and partially generated, such as a Windows Form.

Part of the class is defined in Form1.cs and the designer-generated code is in Form1.designer.cs. Both class contain implementations of the class Form1, but typically the developer doesn't edit the code in the 'designer' file, but can still customize the Form1 class by editing the Form1.cs file

Partial class can be extended. It is used to break up one class into multiple files.
