You can create as many directories and sub-directories as you want in order to group the thin clients together. When you create sub-directories, the thin clients organized in it form sub-groups of a group.
A thin client that is unequivocally identified by its MAC address can only be stored in a single directory, i.e. only as a member of a single group.
To create a directory or sub-directory, proceed as follows:
or select the option New Directory from the context menu of the selected directory.
The new directory will be displayed directly below the selected directory in the structure tree.
You can now move thin clients to this new directory.
