Description
Entering a blank @Folder annotation causes the RD Code Explorer to hide the module.

To Reproduce

1. Paste this annotation in any module: '@Folder("") or '@Folder()
2. Refresh RD.
3. Notice the module has disappeared from Code Explorer.

Expected behavior
If the @Folder annotation doesn't resolve to a legal name then perhaps it can show it in the default folder for that project.

Nice find! I agree without a valid folder a module should show up under the default folder, like the annotation wasn't there.
