When upgrading to 2022.3/4, all old stuff was uninstalled and the folders emptied. I think this means that all custom files, like the unmanage jobs, are gone.
The new path to the jobs seems to be something like "C:\Program Files (x86)\SolarWinds\Orion\Jobs", depending on where you installed your files.
My best guess is that you are looking at restoring those files from backup. They might be in the trashbin, but I would not count on it. I stopped using custom dll, folders, anything the solarwinds directories that were not put there by SolarWinds. I got burned once after inheriting a system, that was one too many times. Things are now converted to swql and stored elsewhere as needed. Seashore Do you have any good news to share in this case?
