ADVANCED ACCESS RIGHTS
The ADVANCED ACCESS RIGHTS function can only be used in
connection with user administration. This function requires the
public directory.
Further information: "Setting advanced file access rights",
Page 457
Upon the first activation of user administration, the public directory
below the TNC: drive will be connected.
Access rights can only be defined for files located in the
public directory.
The control automatically assigns the user function user
as the owner to any files stored on the TNC: drive instead
of the public directory.
Further information: "'public' directory", Page 457
Displaying hidden files
The control hides system files, as well as files and folders whose
name begins with a period.
Caution: Possible loss of data!
The control's operating system uses certain hidden folders
and files. These folders and files are hidden by default. Any
manipulation of the system data within the hidden folders might
damage the control's software. If you save your own files to these
folders, the system will create invalid paths.
Always leave hidden folders and files hidden
Do not use hidden folders and files for saving your own data
If required, you can show the hidden files and folders temporarily,
e.g., if a file whose name begins with a period is transferred
inadvertently.
To show hidden files and folders:
Press the MORE FUNCTIONS soft key
Press the SHOW FILES soft key
The control displays the files and folders.
