Files (e.g. *cara) that are on Network Attach Storage, specifically a Qumulo file system mounted using NFS 3.0, don't appear in the Cara file open dialog(s).
We can provide access to academic users to the NMRbox platform if you wish to see for yourself.
(We can also provide a small development virtual machine (VM) with root access if you want to try / test things.)
