Hi Tessus and everyone,
Thank you for your answer. I checked the FAQ, but I haven’t found any answer for that, nor the documentation. I’ll check again. The Joplin page itself (https://joplin.cozic.net/) is where I found most of the info I have, bur i still don’t know if its possible to export all notes at once.
About the password option in Dropbox, it’s not possible, as I didn’t forgot the password, but the username. I was wondering if its registered somewhere in Joplin’s configurations files.
Thank you for your help,
