Hi all,
i would limit user with SPFT access directory view. Normally when it logged, he see everything from root directory, I think when is possible set his root directory for example to /opt/plcnext/data/'.
Is any way to do in PLCE or directly on PLC?

  thanks

PLCnext Engineer does not include any SFTP management tools (sorry).
This seems to be a general Linux administration issue.
Perhaps something like the top-voted answer to this question might work?

Note that we cannot recommend that users edit configuration files that were installed by the PLCnext Control firmware, although you’re free to do so if you want.
