There's no way for me to upload back to your Google drive.
But just make the same smartlist and erase the files a couple times.
They should stay gone.
If they don't, come back and we'll talk.
Sorry, but you've gone beyond my very limited computer knowledge.
You say, "I made this smartlist:
[Filename]=[] ~d=a
Then I erased the empty files (and again since they go to removed) and now they're gone."
What is [Filename]=[] ~d=a ? I don't know what a "smartlist" is, and I don't understand those symbols.
From where did you erase the empty files?
