When you create a new project, in the projects folder a file with KPF extension will be created,
this file is contains your project information, when you want to open a project you need to select this file
or in explorer you can open this file to open your project. Also the following folders will be created:
||Contains all the forms you create, these files contain only designer and UI information about the forms.
||Contains all the graphs you create, these files contain only graph informations.
||Contains your project executable and any other required files necessary to run your project, you only need to distribute these files.
||Contains your project resources like images and other files that you want to include in the project executable.
||Contains project globalization files.
||This directory is not created by default, you can put external code files (.cs files) in that directory to be compiled into your project.
||Contains all referenced libraries.
Do not rename graph or form files, however in a case where you had to, form and graph file names must be the same.
