You will need to recreate these qvw files in the exact same folder as shown in your screenshot (build a new blank one of copying an existing app), then on the Documents tab in QMC, change the reload schedule to None and Enable them. Then you can delete the dummy apps.
Also make sure that no Document CALs are assigned to these when you set the schedule to None.
Before you delete / rename or move a QVW,
you should ALWAYS ensure that you remove any TASK SCHEDULES and remove / un-assign any document cals. You now need to recreate the OLD qvws in the same original folder with CASE Sensitive original name. You will then be able to disable the schedule and remove any cals. Once done you can safely delete / rename or move your qvws.
