Hello! I keep having this problem, on one tablet this error doesn't show but on another one it does. I have both files in downloads and they have the same name.
The app tells me the file is the existing directory but when I try to open it it appears the error 2102 /downloads/filename.txt could not be opened.
I have the file DefaultScope in "Legacy" (before I had another error when opening the file and this fixed it).
