I had skybox on my PC and used airscreen to view files on my oculus go. I'm unfamiliar with mklink but I had a folder on my external hard drive that skybox was installed to. The files that were deleted were inside the same folder on the external hard drive which is what I'm guessing caused the issue.
(Within my external hard drive (e) there was one folder (1) which contained two folders, one containing the entire Skybox program file, and the other containing all my vr and non vr video files.)
I had everything installed to a hard drive so I could easily transfer between computers as I own multiple. I hope this helps.
