Why can't fm write files to the container field

I am getting this error message when I try to insert a file into a container field set up for external storage:

"Can not write file to the external storage."


The filename is PWNA, the table name is Documents, and the field name is Container.

See the first screenshot:

I thought FM should have automatically created the Documents and Container folders, but it didn’t.

I just created those manually, which has not been necessary when I have implemented this for other clients.

That seems suspicious to me; is there something wrong with the paths as entered in the dialogs that prevented FM from creating those folders?


I have tried two other variants in the Open Storage section; once using just “Documents/“, and once using just “Container/“, but those didn’t work either.
