In the New Java Project wizard, uncheck the checkbox that says Use default location and the use the Browse button to find your directory.

It is pretty easy to do. Go to File->New-> Project. In the Project wizard, choose the type of project you want and then be sure to unclick the 'Use default location` checkbox. Browse for your folder in the widget that then becomes enabled. Click finish after that.

Alternatively, you could create a brand new project workspace in a new location. Then, assuming Java as your project type, you can open up your project properties and add as a source folder your existing directory. To do this, use the 'Link Source' button on the Java Build Path -> Source tab of your Project Properties dialog.
