    The list from which those numbers came was generated within PowerShell. I just looked at them with Windows Explorer and they are all folders. When clicked WE says that these folders are empty. Fortunately I have this aversion to deleting things that I do not know anything about. The reason for the search was that I discovered that programs which have been deleted still have folders and files scattered about. Those I do delete. Thank you for the answer.

    Those are GUIDs (Globally Unique IDentifiers) which are pseduo-randomly generated. They are a result of software installs and are used by the system to uniquely identify software components among other things. You don't indicate if they are files or folders, but it should do no harm leaving them alone and may cause problems if you delete them.
