Hello, first off do you have a external drive of some sort connected to the reaspberry? If not, you would probably want to place them in a a directory in root. So once logged in as root you would type "CD.." and then do a "dir" to see if you are back at root yet, if not "cd.." again. Once there make your directory for uploads "mkdir foldername". After that you will have a place to upload data, if you have external storage you may want to do it there. Hope this helps.
did all go well with this?
we can try testing the service, please check permissions om the raspberry root.
i know what filezilla is, and i understand how a Rasberry works. That's why we need to check permissions.
I'll put ap hone offer in if its easier for us to touch base over phone, if not here is fine, it's just harder when its not in real time. But this sounds like a permissions issue.
