[eclipse] How to import an existing directory into Eclipse?

I Using below simple way to create a project 1- First in a directory that desire to make it project, create a .project file with below contents:

<projectDescription>
    <name>Project-Name</name>
    <comment></comment>
    <projects>
    </projects>
    <buildSpec>
    </buildSpec>
    <natures>
    </natures>
</projectDescription>

2- Now instead of "Project-Name", write your project name, maybe current directory name

3- Now save this file to directory that desire to make that directory as project with name ".project" ( for save like this, use Notepad )

4- Now go to Eclips and open project and add your files to it.
