Together with the release of Unraid 6.10-rc3 comes a new plugin: Dynamix File Manager (DFM).   DFM is an extension to the built-in file browser functionality of the GUI and allows the user to do file management on the array. File operations include copy, move, delete,  rename, upload and download, while it is also possible to change owner and permissions of files and folders.   The attached User Guide gives further explanation of how to use the Dynamix File Manager.
