Try this:
CopyFile[
"/wolframcloud/userfiles/ba9/ba9a1691-48ac-417b-964f-1a1467d3d5a6/model.stl",
CloudObject["model.stl"]
]
I also strongly suspect that the value of $HomeDirectory
for you is "/wolframcloud/userfiles/ba9/ba9a1691-48ac-417b-964f-1a1467d3d5a6/"
, correct?
That means that the file is in your home, but is not a CloudObject
, however it should still be visible in your home (without doing the operation above).
