# Basic multi root API samples

This extension adds an entry to the status bar that shows the name of the currently active file. To exercise multi root APIs it:
- only enables itself when more than one `WorkspaceFolder` is opened using `workspace.workspaceFolders` API
- shows the name of the `WorkspaceFolder` the file is from (if any) using `workspace.getWorkspaceFolder()` API
- updates when there are changes to the number of `WorkspaceFolder` via the `workspace.onDidChangeWorkspaceFolders()` API
- registers a setting `multiRootSample.statusColor` with a scope of `resource` to configure a color per `WorkspaceFolder` to use for the status bar item
