steps to reproduce:

1. have a project (which already exists in your "project view")
2. go to the explorer in vscode and move this folder (or file) somewhere else (so it has a new path)
3. go back to the "project view" and hover over the path (or just look at the path which is saved in the view)
4. BUG: the old file path (before the folder/file was moved) exists instead the new folder/file path should be updated.

The fix is that for each folder or file in the projects view, there should be a watcher/listener to see if that folder or file is moved. If so, the project item should have its uri updated to make the "project view" information correct.

this problem is related to this issue where a deleted folder / file is not reflected in the project view either, incorporate this problem into the solution so deletion of a project from the explorer is reflected in an update to the projects view
