A couple of times I have suspected that Joplin deletes file attachments that are not orphans - and now I have experienced it again.
I understand that Joplin regularly traverse through all attachments to see if they are not linked from any notes - and if they are not Joplin deletes the attachments.
I feel that this is a very dangerous behaviour - and i am beginning to think I can not trust Joplin to store important file attachments anymore.
The problem was discovered now with a note that I have kept for about 9 months now. Each month I add a new file attachment to the note. Now I suddenly discovered that 7 attachments of 8 has been deleted from this note. Only the newest attachment is still available.
Sync method is Dropbox. E2E encryption. My Joplin clients: Android, iOS, Win, Linux.
