Where in an Eclipse workspace is the list of projects stored?
Windows: <workspace>\.metadata\.plugins\org.eclipse.core.resources\.projects\ Linux / osx: <workspace>/.metadata/.plugins/org.eclipse.core.resources/.projects/ Your project can exist outside the workspace, but all Eclipse-specific metadata are stored in that org.eclipse.core.resources\.projects directory As noted in the comments by tk421storm, and in Jeegar Patel’s answer: In order for manual changes to take effect, make sure to do File -> Refresh afterwards.
