I got three times the same issue on NC 25 which shares local folders mounted via NFS.
In my case, nothing happens when I create a new text file in the empty folder. Just synchronized the new file with other NC clients.
Only disconnecting the shared folder and then creating a new local share again I got my old files in the empty directory.
What’s the question of this issue?
Does it depend by use of network protocols: SAMBA or NFS ?
