Missing folder

[Ron1967]

I am very new to TrueNAS.
I lost access to my folder in windows and TrueNAS GUI / Shell.
I was trying to setup an Ubuntu VM and moving files around the time i lost access.
The folder in Windows Explorer shows empty.
The Storage tab in TrueNAS GUI still shows the space used.
In TrueNAS Shell the folder shows in the dir list.
When I try to cd to that folder I get 'Permission denied'.

I think I know at least one issue. I had moved an .iso file to the Dataset Folder. The file is named 'ubuntu-18.04.3-desktop-amd64 (1).iso'. I don't think the space between '. . . amd64' and '(1).iso' is well liked.

Further information. I used this folder when trying to create the VM.
