Can NetOpSchool 6.2's built-in file manager run as system or NetOpActivity user?

Question

Network administration

Question to those who have encountered NetOp School.

There is a folder that students are not allowed to change. Worth NetOp School, the folder is configured to send files from the teacher's computer. To do this, added permission to change for NetOpActivity. The distribution is working.
But the built-in file manager, when you try to change something there, gives an access error. At the same time, it sees all disks, but it seems that it works under the rights of the current user.

How can this be corrected?
