@steveharis22 Not solved, but look the image attached.
When I open Opera, ext-hdd starts but windows monitor shows nothing related to my ext-hdd (letter "D"). But I test importing bookmarks and happens what you see in the capture:
"Taller 4" is where I store my university docs.
"Marcadores_21_7_20.html" is my imported bookmarks file.
"D:$Mft (Tabla maestra de archivos NTFS)" I know what it is, but not what Opera does.
So, what is happening?
