Hi David! I managed to open the downloaded file using the file explorer on the left hand side of my Positron rather than the folder selector you used. Why is my folder selector not visible? Thanks.
Gracielle Higino Coach • September 23, 2026
Hi Kolawole! I can't tell why your folder selector is not visible without more details. Can you share which Positron version you're using? Feel free to book a meeting with me to walk me through your problem if you need.
