Downloading the workspace is probably not a good idea, since you might have different environment and locations.
What I would do is this:
- Create a new workspace or use an existing one
- Open the workspace above
- Use File -> Import ->Existing project to a workspace
- Navigate to the root folder of the project that you want to import
Alternatively in step #4 you can navigate to a root folder of several project, in which case you'll see a dialog where you'll need to select all projects that you want to import. This approach allows importing multiple projects in a single import.
Eclipse finds projects by searching for '.project' files in all sub-directories of the root folder that you've provided.
