JC-120MC File system
6.2 User administration
The file system for the internal flash disk lets you define authorization for
access (locks) to directories, and set up users.
For each user, you can set individual access rights (keys).
Users are not allowed to access directories and files for which they do not
have the required key. In case of an FTP/IP connection, these directories and
files are not displayed.
Administrator rights are required for user administration.
The properties of user administration are as follows:
Property Max. value
Number of users 33
Number of predefined users 2
Length of a user name 31 alphanumeric characters
Password length 31 alphanumeric characters
Number of keys for read access 31
Number of keys for write access 31
Number of predefined keys 2
You can make settings for user administration in three files located in the
directory System :
File Function
flashdisklock.ini Assignment of locks to directories
keys.ini Assignment of names to locks/keys
users.ini Administration of users
These files are always existing. They cannot be deleted, but only modified or
overwritten.
Please take the following restrictions into account:

User administration can only be applied to the internal flash disk. It cannot
be applied to SD cards.
 If user administration has been assigned to a file, its contents are readable
at once. The settings become active only after a reboot.
