Just to make sure you are not actually looking for the results.gdb and source.gdb .... for those, you will need to map to the drive (of you can do the folder) that the .gdb are located using the + icon
Then you should be able to find those. As you can see from the image, I have both the full drive and some subfolders connected. At the root, you have access to all the folders....but sometimes it is more convenient to connect directly tot he folder (e.g. c:\Student )
