What is the impact if we check or uncheck the checkbox Need your help on this .

Thanks .

I think he is more concerned about the check box, The check box tells you wether to create a copy of all the resources in the project you are importing to your workspace or not, and if you keep it unchecked it will just create a .classpatha and .project file ( basically a project ) with all the resources refering to original location.

The screen asked you to select the root directory and not just a single project. It then displays all the projects present in that directory. You can then allow to choose between the projects to import to the workspace.
