TFVC has several folders with guid names at the org root?

Using Azure DevOps Services for source control TFVC. I have an organization with a two projects and repo I'm reviewing for missing files with Team Explorer in VS.

VS Team Explorer => Pending Changes => Detected shows several folders as deleted at the root with guid names that don't correspond to any projects or repos. They also show using tf.exe. Also, >tf info <guid> reports 'No items match'. I'm unable to get or delete.

Anyone know what they are? Thanks.

Solution

They are the deleted TFVC projects from your Azure DevOps organization which used to get mapped with the workspaces on this computer. You may have noticed that every GUID begins with D.

Here is the API you may leverage to get the deleted projects.
