How to get project list if delete .metadata accidentally

Question

if .metadata directory is deleted, is there a way to recover the Eclipse project list?

Answer 1

After you have re-created your workspace, you can re-add projects to your workspace by following these steps:

• Select File :: Import :: Other :: General :: Existing Projects into Workspace
• Browse for the root directory (if the projects share a common parent, like the workspace directory, select that)
• Check all the projects you want to re-import and click Finish

Answer 2

Now that you know where the projects are stored within said metadata..., no there isn't a way to recover that list.
You need to re-import those projects in your workspace.

The name of those project comes from their respective .project file.
